CVE-2023-24492 2 Canonical, Citrix 2 Ubuntu Linux, Secure Access Client 2023-07-20 N/A 8.8 HIGH
A vulnerability has been discovered in the Citrix Secure Access client for Ubuntu which, if exploited, could allow an attacker to remotely execute code if a victim user opens an attacker-crafted link and accepts further prompts.
CVE-2018-16880 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2023-07-19 6.9 MEDIUM 7.0 HIGH
A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest, under specific conditions, can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. Versions from v4.16 and newer are vulnerable.
CVE-2019-14816 7 Canonical, Debian, Fedoraproject and 4 more 54 Ubuntu Linux, Debian Linux, Fedora and 51 more 2023-07-12 7.2 HIGH 7.8 HIGH
There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.
CVE-2021-3493 1 Canonical 1 Ubuntu Linux 2023-07-07 7.2 HIGH 7.8 HIGH
The overlayfs implementation in the linux kernel did not properly validate with respect to user namespaces the setting of file capabilities on files in an underlying file system. Due to the combination of unprivileged user namespaces along with a patch carried in the Ubuntu kernel to allow unprivileged overlay mounts, an attacker could use this to gain elevated privileges.
CVE-2022-29581 4 Canonical, Debian, Linux and 1 more 19 Ubuntu Linux, Debian Linux, Linux Kernel and 16 more 2023-06-28 7.2 HIGH 7.8 HIGH
Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions.
CVE-2019-6706 2 Canonical, Lua 2 Ubuntu Linux, Lua 2023-06-23 5.0 MEDIUM 7.5 HIGH
Lua 5.3.5 has a use-after-free in lua_upvaluejoin in lapi.c. For example, a crash outcome might be achieved by an attacker who is able to trigger a debug.upvaluejoin call in which the arguments have certain relationships.
CVE-2023-2612 1 Canonical 1 Ubuntu Linux 2023-06-22 N/A 4.7 MEDIUM
Jean-Baptiste Cayrou discovered that the shiftfs file system in the Ubuntu Linux kernel contained a race condition when handling inode locking in some situations. A local attacker could use this to cause a denial of service (kernel deadlock).
CVE-2013-6629 9 Artifex, Canonical, Debian and 6 more 12 Gpl Ghostscript, Ubuntu Linux, Debian Linux and 9 more 2023-06-21 5.0 MEDIUM N/A
The get_sos function in jdmarker.c in (1) libjpeg 6b and (2) libjpeg-turbo through 1.3.0, as used in Google Chrome before 31.0.1650.48, Ghostscript, and other products, does not check for certain duplications of component data during the reading of segments that follow Start Of Scan (SOS) JPEG markers, which allows remote attackers to obtain sensitive information from uninitialized memory locations via a crafted JPEG image.
CVE-2018-1068 4 Canonical, Debian, Linux and 1 more 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more 2023-06-21 7.2 HIGH 6.7 MEDIUM
A flaw was found in the Linux 4.x kernel's implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory.
CVE-2023-32549 1 Canonical 1 Landscape 2023-06-16 N/A 7.5 HIGH
Landscape cryptographic keys were insecurely generated with a weak pseudo-random generator.
CVE-2023-32550 1 Canonical 1 Landscape 2023-06-15 N/A 8.2 HIGH
Landscape's server-status page exposed sensitive system information. This data leak included GET requests which contain information to attack and leak further information from the Landscape API.
CVE-2023-32551 1 Canonical 1 Landscape 2023-06-14 N/A 6.1 MEDIUM
Landscape allowed URLs which caused open redirection.
CVE-2021-3939 1 Canonical 2 Accountsservice, Ubuntu Linux 2023-06-12 7.2 HIGH 7.8 HIGH
Ubuntu-specific modifications to accountsservice (in patch file debian/patches/0010-set-language.patch) caused the fallback_locale variable, pointing to static storage, to be freed, in the user_change_language_authorized_cb function. This is reachable via the SetLanguage dbus function. This is fixed in versions 0.6.55-0ubuntu12~20.04.5, 0.6.55-0ubuntu13.3, 0.6.55-0ubuntu14.1.
CVE-2020-12861 3 Canonical, Opensuse, Sane-project 3 Ubuntu Linux, Leap, Sane Backends 2023-06-12 7.9 HIGH 8.8 HIGH
A heap buffer overflow in SANE Backends before 1.0.30 allows a malicious device connected to the same local network as the victim to execute arbitrary code, aka GHSL-2020-080.
CVE-2020-12049 2 Canonical, Freedesktop 2 Ubuntu Linux, Dbus 2023-06-12 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in dbus >= 1.3.0 before 1.12.18. The DBusServer in libdbus, as used in dbus-daemon, leaks file descriptors when a message exceeds the per-message file descriptor limit. A local attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket could use this to make the system service reach its file descriptor limit, denying service to subsequent D-Bus clients.
CVE-2019-7307 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-06-12 4.4 MEDIUM 7.0 HIGH
Apport before versions 2.14.1-0ubuntu3.29+esm1, 2.20.1-0ubuntu2.19, 2.20.9-0ubuntu7.7, 2.20.10-0ubuntu27.1, 2.20.11-0ubuntu5 contained a TOCTTOU vulnerability when reading the users ~/.apport-ignore.xml file, which allows a local attacker to replace this file with a symlink to any other file on the system and so cause Apport to include the contents of this other file in the resulting crash report. The crash report could then be read by that user either by causing it to be uploaded and reported to Launchpad, or by leveraging some other vulnerability to read the resulting crash report, and so allow the user to read arbitrary files on the system.
CVE-2019-15790 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-06-12 2.1 LOW 3.3 LOW
Apport reads and writes information on a crashed process to /proc/pid with elevated privileges. Apport then determines which user the crashed process belongs to by reading /proc/pid through get_pid_info() in data/apport. An unprivileged user could exploit this to read information about a privileged running process by exploiting PID recycling. This information could then be used to obtain ASLR offsets for a process with an existing memory corruption vulnerability. The initial fix introduced regressions in the Python Apport library due to a missing argument in Report.add_proc_environ in apport/report.py. It also caused an autopkgtest failure when reading /proc/pid and with Python 2 compatibility by reading /proc maps. The initial and subsequent regression fixes are in 2.20.11-0ubuntu16, 2.20.11-0ubuntu8.6, 2.20.9-0ubuntu7.12, 2.20.1-0ubuntu2.22 and 2.14.1-0ubuntu3.29+esm3.
CVE-2019-11484 2 Canonical, Whoopsie Project 2 Ubuntu Linux, Whoopsie 2023-06-12 4.6 MEDIUM 7.8 HIGH
Kevin Backhouse discovered an integer overflow in bson_ensure_space, as used in whoopsie.
CVE-2019-11481 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2023-06-12 6.1 MEDIUM 7.8 HIGH
Kevin Backhouse discovered that apport would read a user-supplied configuration file with elevated privileges. By replacing the file with a symbolic link, a user could get apport to read any file on the system as root, with unknown consequences.
CVE-2019-11476 1 Canonical 1 Ubuntu Linux 2023-06-12 4.6 MEDIUM 7.8 HIGH
An integer overflow in whoopsie before versions 0.2.52.5ubuntu0.1, 0.2.62ubuntu0.1, 0.2.64ubuntu0.1, 0.2.66, results in an out-of-bounds write to a heap allocated buffer when processing large crash dumps. This results in a crash or possible code-execution in the context of the whoopsie process.
