CVE-2019-10904 2 Debian, Roundup-tracker 2 Debian Linux, Roundup 2019-04-09 4.3 MEDIUM 6.1 MEDIUM
Roundup 1.6 allows XSS via the URI because frontends/roundup.cgi and roundup/cgi/wsgi_handler.py mishandle 404 errors.
CVE-2017-1000410 3 Debian, Linux, Redhat 9 Debian Linux, Linux Kernel, Enterprise Linux Desktop and 6 more 2019-04-08 5.0 MEDIUM 7.5 HIGH
The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state. By manipulating the code flows that precede the handling of these configuration messages, an attacker can also gain some control over which data will be held in the uninitialized stack variables. This can allow him to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in this manner. Combining this vulnerability (for example) with the previously disclosed RCE vulnerability in L2CAP configuration parsing (CVE-2017-1000251) may allow an attacker to exploit the RCE against kernels which were built with the above mitigations. These are the specifics of this vulnerability: In the function l2cap_parse_conf_rsp and in the function l2cap_parse_conf_req the following variable is declared without initialization: struct l2cap_conf_efs efs; In addition, when parsing input configuration parameters in both of these functions, the switch case for handling EFS elements may skip the memcpy call that will write to the efs variable: ... case L2CAP_CONF_EFS: if (olen == sizeof(efs)) memcpy(&efs, (void *)val, olen); ... The olen in the above if is attacker controlled, and regardless of that if, in both of these functions the efs variable would eventually be added to the outgoing configuration request that is being built: l2cap_add_conf_opt(&ptr, L2CAP_CONF_EFS, sizeof(efs), (unsigned long) &efs); So by sending a configuration request, or response, that contains an L2CAP_CONF_EFS element, but with an element length that is not sizeof(efs) - the memcpy to the uninitialized efs variable can be avoided, and the uninitialized variable would be returned to the attacker (16 bytes).
CVE-2018-17000 3 Canonical, Debian, Libtiff 3 Ubuntu Linux, Debian Linux, Libtiff 2019-04-05 4.3 MEDIUM 6.5 MEDIUM
A NULL pointer dereference in the function _TIFFmemcmp at tif_unix.c (called from TIFFWriteDirectoryTagTransferfunction) in LibTIFF 4.0.9 allows an attacker to cause a denial-of-service through a crafted tiff file. This vulnerability can be triggered by the executable tiffcp.
CVE-2018-20544 3 Canonical, Debian, Libcaca Project 3 Ubuntu Linux, Debian Linux, Libcaca 2019-04-05 4.3 MEDIUM 6.5 MEDIUM
There is floating point exception at caca/dither.c (function caca_dither_bitmap) in libcaca 0.99.beta19.
CVE-2005-3912 2 Debian, Webmin 2 Debian Linux, Webmin 2019-04-03 7.5 HIGH N/A
Format string vulnerability in miniserv.pl Perl web server in Webmin before 1.250 and Usermin before 1.180, with syslog logging enabled, allows remote attackers to cause a denial of service (crash or memory consumption) and possibly execute arbitrary code via format string specifiers in the username parameter to the login form, which is ultimately used in a syslog call. NOTE: the code execution might be associated with an issue in Perl.
CVE-2019-6250 2 Debian, Zeromq 2 Debian Linux, Libzmq 2019-04-03 9.0 HIGH 8.8 HIGH
A pointer overflow, with code execution, was discovered in ZeroMQ libzmq (aka 0MQ) 4.2.x and 4.3.x before 4.3.1. A v2_decoder.cpp zmq::v2_decoder_t::size_ready integer overflow allows an authenticated attacker to overwrite an arbitrary amount of bytes beyond the bounds of a buffer, which can be leveraged to run arbitrary code on the target system. The memory layout allows the attacker to inject OS commands into a data structure located immediately after the problematic buffer (i.e., it is not necessary to use a typical buffer-overflow exploitation technique that changes the flow of control).
CVE-2018-18710 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-04-03 2.1 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel through 4.19. An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658.
CVE-2018-12896 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-04-03 2.1 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel through 4.17.3. An Integer Overflow in kernel/time/posix-timers.c in the POSIX timer code is caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically makes the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. For example, a local user can cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls.
CVE-2018-18021 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-04-03 3.6 LOW 7.1 HIGH
arch/arm64/kvm/guest.c in KVM in the Linux kernel before 4.18.12 on the arm64 platform mishandles the KVM_SET_ON_REG ioctl. This is exploitable by attackers who can create virtual machines. An attacker can arbitrarily redirect the hypervisor flow of control (with full register control). An attacker can also cause a denial of service (hypervisor panic) via an illegal exception return. This occurs because of insufficient restrictions on userspace access to the core register file, and because PSTATE.M validation does not prevent unintended execution modes.
CVE-2018-13100 2 Debian, Linux 2 Debian Linux, Linux Kernel 2019-04-03 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in fs/f2fs/super.c in the Linux kernel through 4.17.3, which does not properly validate secs_per_zone in a corrupted f2fs image, as demonstrated by a divide-by-zero error.
CVE-2017-18249 2 Debian, Linux 2 Debian Linux, Linux Kernel 2019-04-03 4.4 MEDIUM 7.0 HIGH
The add_free_nid function in fs/f2fs/node.c in the Linux kernel before 4.12 does not properly track an allocated nid, which allows local users to cause a denial of service (race condition) or possibly have unspecified other impact via concurrent threads.
CVE-2018-18501 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Firefox and 7 more 2019-04-02 7.5 HIGH 9.8 CRITICAL
Mozilla developers and community members reported memory safety bugs present in Firefox 64 and Firefox ESR 60.4. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.
CVE-2018-18500 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2019-04-02 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur while parsing an HTML5 stream in concert with custom HTML elements. This results in the stream parser object being freed while still in use, leading to a potentially exploitable crash. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.
CVE-2018-20511 2 Debian, Linux 2 Debian Linux, Linux Kernel 2019-04-01 2.1 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel before 4.18.11. The ipddp_ioctl function in drivers/net/appletalk/ipddp.c allows local users to obtain sensitive kernel address information by leveraging CAP_NET_ADMIN to read the ipddp_route dev and next fields via an SIOCFINDIPDDPRT ioctl call.
CVE-2018-16862 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2019-04-01 2.1 LOW 5.5 MEDIUM
A security flaw was found in the Linux kernel in a way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one.
CVE-2018-6392 2 Debian, Ffmpeg 2 Debian Linux, Ffmpeg 2019-03-31 4.3 MEDIUM 6.5 MEDIUM
The filter_slice function in libavfilter/vf_transpose.c in FFmpeg through 3.4.1 allows remote attackers to cause a denial of service (out-of-array access) via a crafted MP4 file.
CVE-2018-13006 3 Canonical, Debian, Gpac 3 Ubuntu Linux, Debian Linux, Gpac 2019-03-29 7.5 HIGH 9.8 CRITICAL
An issue was discovered in MP4Box in GPAC 0.7.1. There is a heap-based buffer over-read in the isomedia/box_dump.c function hdlr_dump.
CVE-2018-13005 3 Canonical, Debian, Gpac 3 Ubuntu Linux, Debian Linux, Gpac 2019-03-29 7.5 HIGH 9.8 CRITICAL
An issue was discovered in MP4Box in GPAC 0.7.1. The function urn_Read in isomedia/box_code_base.c has a heap-based buffer over-read.
CVE-2018-12892 2 Debian, Xen 2 Debian Linux, Xen 2019-03-29 6.5 MEDIUM 9.9 CRITICAL
An issue was discovered in Xen 4.7 through 4.10.x. libxl fails to pass the readonly flag to qemu when setting up a SCSI disk, due to what was probably an erroneous merge conflict resolution. Malicious guest administrators or (in some situations) users may be able to write to supposedly read-only disk images. Only emulated SCSI disks (specified as "sd" in the libxl disk configuration, or an equivalent) are affected. IDE disks ("hd") are not affected (because attempts to make them readonly are rejected). Additionally, CDROM devices (that is, devices specified to be presented to the guest as CDROMs, regardless of the nature of the backing storage on the host) are not affected; they are always read only. Only systems using qemu-xen (rather than qemu-xen-traditional) as the device model version are vulnerable. Only systems using libxl or libxl-based toolstacks are vulnerable. (This includes xl, and libvirt with the libxl driver.) The vulnerability is present in Xen versions 4.7 and later. (In earlier versions, provided that the patch for XSA-142 has been applied, attempts to create read only disks are rejected.) If the host and guest together usually support PVHVM, the issue is exploitable only if the malicious guest administrator has control of the guest kernel or guest kernel command line.
CVE-2018-12227 2 Debian, Digium 3 Debian Linux, Asterisk, Certified Asterisk 2019-03-29 5.0 MEDIUM 5.3 MEDIUM
An issue was discovered in Asterisk Open Source 13.x before 13.21.1, 14.x before 14.7.7, and 15.x before 15.4.1 and Certified Asterisk 13.18-cert before 13.18-cert4 and 13.21-cert before 13.21-cert2. When endpoint specific ACL rules block a SIP request, they respond with a 403 forbidden. However, if an endpoint is not identified, then a 401 unauthorized response is sent. This vulnerability just discloses which requests hit a defined endpoint. The ACL rules cannot be bypassed to gain access to the disclosed endpoints.
