CVE-2018-1116 3 Canonical, Debian, Polkit Project 3 Ubuntu Linux, Debian Linux, Polkit 2020-05-05 3.6 LOW 4.4 MEDIUM
A flaw was found in polkit before version 0.116. The implementation of the polkit_backend_interactive_authority_check_authorization function in polkitd allows to test for authentication and trigger authentication of unrelated processes owned by other users. This may result in a local DoS and information disclosure.
CVE-2019-16234 3 Canonical, Linux, Opensuse 3 Ubuntu Linux, Linux Kernel, Leap 2020-05-05 4.7 MEDIUM 4.7 MEDIUM
drivers/net/wireless/intel/iwlwifi/pcie/trans.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.
CVE-2019-16231 4 Canonical, Linux, Opensuse and 1 more 4 Ubuntu Linux, Linux Kernel, Leap and 1 more 2020-05-04 4.7 MEDIUM 4.1 MEDIUM
drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.
CVE-2018-11235 5 Canonical, Debian, Git-scm and 2 more 9 Ubuntu Linux, Debian Linux, Git and 6 more 2020-05-02 6.8 MEDIUM 7.8 HIGH
In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x before 2.15.2, 2.16.x before 2.16.4, and 2.17.x before 2.17.1, remote code execution can occur. With a crafted .gitmodules file, a malicious project can execute an arbitrary script on a machine that runs "git clone --recurse-submodules" because submodule "names" are obtained from this file, and then appended to $GIT_DIR/modules, leading to directory traversal with "../" in a name. Finally, post-checkout hooks from a submodule are executed, bypassing the intended design in which hooks are not obtained from a remote server.
CVE-2018-11233 2 Canonical, Git-scm 2 Ubuntu Linux, Git 2020-05-02 5.0 MEDIUM 7.5 HIGH
In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x before 2.15.2, 2.16.x before 2.16.4, and 2.17.x before 2.17.1, code to sanity-check pathnames on NTFS can result in reading out-of-bounds memory.
CVE-2017-15298 2 Canonical, Git-scm 2 Ubuntu Linux, Git 2020-05-02 4.3 MEDIUM 5.5 MEDIUM
Git through 2.14.2 mishandles layers of tree objects, which allows remote attackers to cause a denial of service (memory consumption) via a crafted repository, aka a Git bomb. This can also have an impact of disk consumption; however, an affected process typically would not survive its attempt to build the data structure in memory before writing to disk.
CVE-2019-15791 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2020-05-01 4.6 MEDIUM 7.8 HIGH
In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfs_btrfs_ioctl_fd_replace() installs an fd referencing a file from the lower filesystem without taking an additional reference to that file. After the btrfs ioctl completes this fd is closed, which then puts a reference to that file, leading to a refcount underflow.
CVE-2019-15792 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2020-05-01 4.6 MEDIUM 7.8 HIGH
In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfs_btrfs_ioctl_fd_replace() calls fdget(oldfd), then without further checks passes the resulting file* into shiftfs_real_fdget(), which casts file->private_data, a void* that points to a filesystem-dependent type, to a "struct shiftfs_file_info *". As the private_data is not required to be a pointer, an attacker can use this to cause a denial of service or possibly execute arbitrary code.
CVE-2019-15793 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2020-05-01 4.6 MEDIUM 8.8 HIGH
In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, several locations which shift ids translate user/group ids before performing operations in the lower filesystem were translating them into init_user_ns, whereas they should have been translated into the s_user_ns for the lower filesystem. This resulted in using ids other than the intended ones in the lower fs, which likely did not map into the shifts s_user_ns. A local attacker could use this to possibly bypass discretionary access control permissions.
CVE-2017-6512 3 Canonical, Debian, File\ 3 Ubuntu Linux, Debian Linux, \ 2020-04-29 4.3 MEDIUM 5.9 MEDIUM
Race condition in the rmtree and remove_tree functions in the File-Path module before 2.13 for Perl allows attackers to set the mode on arbitrary files via vectors involving directory-permission loosening logic.
CVE-2015-3451 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2020-04-29 5.0 MEDIUM N/A
The _clone function in XML::LibXML before 2.0119 does not properly set the expand_entities option, which allows remote attackers to conduct XML external entity (XXE) attacks via crafted XML data to the (1) new or (2) load_xml function.
CVE-2016-2073 3 Canonical, Debian, Xmlsoft 3 Ubuntu Linux, Debian Linux, Libxml2 2020-04-23 4.3 MEDIUM 6.5 MEDIUM
The htmlParseNameComplex function in HTMLparser.c in libxml2 allows attackers to cause a denial of service (out-of-bounds read) via a crafted XML document.
CVE-2018-19542 5 Canonical, Debian, Jasper Project and 2 more 6 Ubuntu Linux, Debian Linux, Jasper and 3 more 2020-04-15 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in JasPer 2.0.14. There is a NULL pointer dereference in the function jp2_decode in libjasper/jp2/jp2_dec.c, leading to a denial of service.
CVE-2015-7747 3 Audio File Library Project, Canonical, Fedoraproject 3 Audio File Library, Ubuntu Linux, Fedora 2020-04-13 6.8 MEDIUM 8.8 HIGH
Buffer overflow in the afReadFrames function in audiofile (aka libaudiofile and Audio File Library) allows user-assisted remote attackers to cause a denial of service (program crash) or possibly execute arbitrary code via a crafted audio file, as demonstrated by sixteen-stereo-to-eight-mono.c.
CVE-2018-13440 2 Audio File Library Project, Canonical 2 Audio File Library, Ubuntu Linux 2020-04-13 4.3 MEDIUM 6.5 MEDIUM
The audiofile Audio File Library 0.3.6 has a NULL pointer dereference bug in ModuleState::setup in modules/ModuleState.cpp, which allows an attacker to cause a denial of service via a crafted caf file, as demonstrated by sfconvert.
CVE-2019-15795 3 Canonical, Debian, Ubuntu 3 Ubuntu Linux, Python-apt, Python-apt 2020-04-08 2.6 LOW 4.7 MEDIUM
python-apt only checks the MD5 sums of downloaded files in `Version.fetch_binary()` and `Version.fetch_source()` of apt/package.py in version 1.9.0ubuntu1 and earlier. This allows a man-in-the-middle attack which could potentially be used to install altered packages and has been fixed in versions 1.9.0ubuntu1.2, 1.6.5ubuntu0.1, 1.1.0~beta1ubuntu0.16.04.7, 0.9.3.5ubuntu3+esm2, and 0.8.3ubuntu7.5.
CVE-2012-3954 3 Canonical, Debian, Isc 3 Ubuntu Linux, Debian Linux, Dhcp 2020-04-01 3.3 LOW N/A
Multiple memory leaks in ISC DHCP 4.1.x and 4.2.x before 4.2.4-P1 and 4.1-ESV before 4.1-ESV-R6 allow remote attackers to cause a denial of service (memory consumption) by sending many requests.
CVE-2015-8605 4 Canonical, Debian, Isc and 1 more 4 Ubuntu Linux, Debian Linux, Dhcp and 1 more 2020-04-01 5.7 MEDIUM 6.5 MEDIUM
ISC DHCP 4.x before 4.1-ESV-R12-P1, 4.2.x, and 4.3.x before 4.3.3-P1 allows remote attackers to cause a denial of service (application crash) via an invalid length field in a UDP IPv4 packet.
CVE-2012-3571 3 Canonical, Debian, Isc 3 Ubuntu Linux, Debian Linux, Dhcp 2020-04-01 6.1 MEDIUM N/A
ISC DHCP 4.1.2 through 4.2.4 and 4.1-ESV before 4.1-ESV-R6 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a malformed client identifier.
CVE-2011-4539 3 Canonical, Debian, Isc 3 Ubuntu Linux, Debian Linux, Dhcp 2020-04-01 5.0 MEDIUM N/A
dhcpd in ISC DHCP 4.x before 4.2.3-P1 and 4.1-ESV before 4.1-ESV-R4 does not properly handle regular expressions in dhcpd.conf, which allows remote attackers to cause a denial of service (daemon crash) via a crafted request packet.
