LibVNC before commit ca2a5ac02fbbadd0a21fabba779c1ea69173d10b contains heap use-after-free vulnerability in server code of file transfer extension that can result remote code execution.
CVE-2018-15126 3 Canonical, Debian, Libvnc Project 3 Ubuntu Linux, Debian Linux, Libvncserver 2019-10-31 7.5 HIGH 9.8 CRITICAL
LibVNC before commit 73cb96fec028a576a5a24417b57723b55854ad7b contains heap use-after-free vulnerability in server code of file transfer extension that can result remote code execution
CVE-2008-2009 2 Canonical, Xiph.org 2 Ubuntu Linux, Libvorbis 2019-10-29 4.3 MEDIUM N/A
Xiph.org libvorbis before 1.0 does not properly check for underpopulated Huffman trees, which allows remote attackers to cause a denial of service (crash) via a crafted OGG file that triggers memory corruption during execution of the _make_decode_tree function.
CVE-2013-4238 3 Canonical, Opensuse, Python 3 Ubuntu Linux, Opensuse, Python 2019-10-25 4.3 MEDIUM N/A
The ssl.match_hostname function in the SSL module in Python 2.6 through 3.4 does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
CVE-2018-14665 4 Canonical, Debian, Redhat and 1 more 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more 2019-10-22 7.2 HIGH 6.6 MEDIUM
A flaw was found in xorg-x11-server before 1.20.3. An incorrect permission check for -modulepath and -logfile options when starting Xorg. X server allows unprivileged users with the ability to log in to the system via physical console to escalate their privileges and run arbitrary code under root privileges.
CVE-2005-0758 2 Canonical, Gnu 2 Ubuntu Linux, Gzip 2019-10-16 4.6 MEDIUM N/A
zgrep in gzip before 1.3.5 does not properly sanitize arguments, which allows local users to execute arbitrary commands via filenames that are injected into a sed script.
CVE-2018-18065 5 Canonical, Debian, Net-snmp and 2 more 10 Ubuntu Linux, Debian Linux, Net-snmp and 7 more 2019-10-16 4.0 MEDIUM 6.5 MEDIUM
_set_key in agent/helpers/table_container.c in Net-SNMP before 5.8 has a NULL Pointer Exception bug that can be used by an authenticated attacker to remotely cause the instance to crash via a crafted UDP packet, resulting in Denial of Service.
CVE-2019-3825 3 Canonical, Gnome, Redhat 3 Ubuntu Linux, Gnome Display Manager, Enterprise Linux 2019-10-09 6.9 MEDIUM 6.4 MEDIUM
A vulnerability was discovered in gdm before 3.31.4. When timed login is enabled in configuration, an attacker could bypass the lock screen by selecting the timed login user and waiting for the timer to expire, at which time they would gain access to the logged-in user's session.
CVE-2018-6559 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2019-10-09 2.1 LOW 3.3 LOW
The Linux kernel, as used in Ubuntu 18.04 LTS and Ubuntu 18.10, allows local users to obtain names of files in which they would not normally be able to access via an overlayfs mount inside of a user namespace.
CVE-2018-6555 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-10-09 7.2 HIGH 7.8 HIGH
The irda_setsockopt function in net/irda/af_irda.c and later in drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket.
CVE-2018-6554 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-10-09 4.9 MEDIUM 5.5 MEDIUM
Memory leak in the irda_bind function in net/irda/af_irda.c and later in drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket.
CVE-2018-5381 4 Canonical, Debian, Quagga and 1 more 5 Ubuntu Linux, Debian Linux, Quagga and 2 more 2019-10-09 5.0 MEDIUM 7.5 HIGH
The Quagga BGP daemon (bgpd) prior to version 1.2.3 has a bug in its parsing of "Capabilities" in BGP OPEN messages, in the bgp_packet.c:bgp_capability_msg_parse function. The parser can enter an infinite loop on invalid capabilities if a Multi-Protocol capability does not have a recognized AFI/SAFI, causing a denial of service.
CVE-2018-5380 4 Canonical, Debian, Quagga and 1 more 5 Ubuntu Linux, Debian Linux, Quagga and 2 more 2019-10-09 4.0 MEDIUM 4.3 MEDIUM
The Quagga BGP daemon (bgpd) prior to version 1.2.3 can overrun internal BGP code-to-string conversion tables used for debug by 1 pointer value, based on input.
CVE-2018-5379 5 Canonical, Debian, Quagga and 2 more 10 Ubuntu Linux, Debian Linux, Quagga and 7 more 2019-10-09 7.5 HIGH 9.8 CRITICAL
The Quagga BGP daemon (bgpd) prior to version 1.2.3 can double-free memory when processing certain forms of UPDATE message, containing cluster-list and/or unknown attributes. A successful attack could cause a denial of service or potentially allow an attacker to execute arbitrary code.
CVE-2018-5378 3 Canonical, Debian, Quagga 3 Ubuntu Linux, Debian Linux, Quagga 2019-10-09 4.9 MEDIUM 5.9 MEDIUM
The Quagga BGP daemon (bgpd) prior to version 1.2.3 does not properly bounds check the data sent with a NOTIFY to a peer, if an attribute length is invalid. Arbitrary data from the bgpd process may be sent over the network to a peer and/or bgpd may crash.
CVE-2018-1130 4 Canonical, Debian, Linux and 1 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2019-10-09 4.9 MEDIUM 5.5 MEDIUM
Linux kernel before version 4.16-rc7 is vulnerable to a null pointer dereference in dccp_write_xmit() function in net/dccp/output.c in that allows a local user to cause a denial of service by a number of certain crafted system calls.
CVE-2018-1120 4 Canonical, Debian, Linux and 1 more 7 Ubuntu Linux, Debian Linux, Linux Kernel and 4 more 2019-10-09 3.5 LOW 5.3 MEDIUM
A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file onto a process's memory containing command line arguments (or environment strings), an attacker can cause utilities from psutils or procps (such as ps, w) or any other program which makes a read() call to the /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some controlled time (as a synchronization primitive for other attacks).
CVE-2018-1106 4 Canonical, Debian, Packagekit Project and 1 more 9 Ubuntu Linux, Debian Linux, Packagekit and 6 more 2019-10-09 2.1 LOW 5.5 MEDIUM
An authentication bypass flaw has been found in PackageKit before 1.1.10 that allows users without administrator privileges to install signed packages. A local attacker can use this vulnerability to install vulnerable packages to further compromise a system.
CVE-2018-1087 4 Canonical, Debian, Linux and 1 more 11 Ubuntu Linux, Debian Linux, Linux Kernel and 8 more 2019-10-09 4.6 MEDIUM 7.8 HIGH
kernel KVM before versions kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 and kernel 4.17-rc3 is vulnerable to a flaw in the way the Linux kernel's KVM hypervisor handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first instruction after the stack switch is executed. An unprivileged KVM guest user could use this flaw to crash the guest or, potentially, escalate their privileges in the guest.
CVE-2018-1053 4 Canonical, Debian, Postgresql and 1 more 4 Ubuntu Linux, Debian Linux, Postgresql and 1 more 2019-10-09 3.3 LOW 7.0 HIGH
In postgresql 9.3.x before 9.3.21, 9.4.x before 9.4.16, 9.5.x before 9.5.11, 9.6.x before 9.6.7 and 10.x before 10.2, pg_upgrade creates file in current working directory containing the output of `pg_dumpall -g` under umask which was in effect when the user invoked pg_upgrade, and not under 0077 which is normally used for other temporary files. This can allow an authenticated attacker to read or modify the one file, which may contain encrypted or unencrypted database passwords. The attack is infeasible if a directory mode blocks the attacker searching the current working directory or if the prevailing umask blocks the attacker opening the file.
