CVE-2020-8834 5 Canonical, Ibm, Linux and 2 more 5 Ubuntu Linux, Power8, Linux Kernel and 2 more 2024-09-16 6.5 Medium
KVM in the Linux kernel on Power8 processors has a conflicting use of HSTATE_HOST_R1 to store r1 state in kvmppc_hv_entry plus in kvmppc_{save,restore}_tm, leading to a stack corruption. Because of this, an attacker with the ability run code in kernel space of a guest VM can cause the host kernel to panic. There were two commits that, according to the reporter, introduced the vulnerability: f024ee098476 ("KVM: PPC: Book3S HV: Pull out TM state save/restore into separate procedures") 87a11bb6a7f7 ("KVM: PPC: Book3S HV: Work around XER[SO] bug in fake suspend mode") The former landed in 4.8, the latter in 4.17. This was fixed without realizing the impact in 4.18 with the following three commits, though it's believed the first is the only strictly necessary commit: 6f597c6b63b6 ("KVM: PPC: Book3S PR: Add guest MSR parameter for kvmppc_save_tm()/kvmppc_restore_tm()") 7b0e827c6970 ("KVM: PPC: Book3S HV: Factor fake-suspend handling out of kvmppc_save/restore_tm") 009c872a8bc4 ("KVM: PPC: Book3S PR: Move kvmppc_save_tm/kvmppc_restore_tm to separate file")
CVE-2018-15687 2 Canonical, Systemd Project 2 Ubuntu Linux, Systemd 2024-09-16 7.0 High
A race condition in chown_one() of systemd allows an attacker to cause systemd to set arbitrary permissions on arbitrary files. Affected releases are systemd versions up to and including 239.
CVE-2017-15105 3 Canonical, Debian, Nlnetlabs 3 Ubuntu Linux, Debian Linux, Unbound 2024-09-16 N/A
A flaw was found in the way unbound before 1.6.8 validated wildcard-synthesized NSEC records. An improperly validated wildcard NSEC record could be used to prove the non-existence (NXDOMAIN answer) of an existing wildcard record, or trick unbound into accepting a NODATA proof.
CVE-2013-1055 1 Canonical 2 Ubuntu Linux, Unity-firefox-extension 2024-09-16 4.3 Medium
The unity-firefox-extension package could be tricked into dropping a C callback which was still in use, which Firefox would then free, causing Firefox to crash. This could be achieved by adding an action to the launcher and updating it with new callbacks until the libunity-webapps rate limit was hit. Fixed in 3.0.0+14.04.20140416-0ubuntu1.14.04.1 of unity-firefox-extension and in all versions of libunity-webapps by shipping an empty unity-firefox-extension package, thus disabling the extension entirely and invalidating the attack against the libunity-webapps package.
CVE-2019-15789 1 Canonical 1 Microk8s 2024-09-16 8.8 High
Privilege escalation vulnerability in MicroK8s allows a low privilege user with local access to obtain root access to the host by provisioning a privileged container. Fixed in MicroK8s 1.15.3.
CVE-2019-11038 8 Canonical, Debian, Fedoraproject and 5 more 14 Ubuntu Linux, Debian Linux, Fedora and 11 more 2024-09-16 5.3 Medium
When using the gdImageCreateFromXbm() function in the GD Graphics Library (aka LibGD) 2.2.5, as used in the PHP GD extension in PHP versions 7.1.x below 7.1.30, 7.2.x below 7.2.19 and 7.3.x below 7.3.6, it is possible to supply data that will cause the function to use the value of uninitialized variable. This may lead to disclosing contents of the stack that has been left there by previous code.
CVE-2014-1426 1 Canonical 1 Metal As A Service 2024-09-16 N/A
A vulnerability in maasserver.api.get_file_by_name of Ubuntu MAAS allows unauthenticated network clients to download any file. This issue affects: Ubuntu MAAS versions prior to 1.9.2.
CVE-2018-11780 4 Apache, Canonical, Debian and 1 more 4 Spamassassin, Ubuntu Linux, Debian Linux and 1 more 2024-09-16 N/A
A potential Remote Code Execution bug exists with the PDFInfo plugin in Apache SpamAssassin before 3.4.2.
CVE-2020-8833 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2024-09-16 5.6 Medium
Time-of-check Time-of-use Race Condition vulnerability on crash report ownership change in Apport allows for a possible privilege escalation opportunity. If fs.protected_symlinks is disabled, this can be exploited between the os.open and os.chown calls when the Apport cron script clears out crash files of size 0. A symlink with the same name as the deleted file can then be created upon which chown will be called, changing the file owner to root. Fixed in versions 2.20.1-0ubuntu2.23, 2.20.9-0ubuntu7.14, 2.20.11-0ubuntu8.8 and 2.20.11-0ubuntu22.
CVE-2017-13168 2 Canonical, Google 2 Ubuntu Linux, Android 2024-09-16 N/A
An elevation of privilege vulnerability in the kernel scsi driver. Product: Android. Versions: Android kernel. Android ID A-65023233.
CVE-2018-8789 3 Canonical, Debian, Freerdp 3 Ubuntu Linux, Debian Linux, Freerdp 2024-09-16 N/A
FreeRDP prior to version 2.0.0-rc4 contains several Out-Of-Bounds Reads in the NTLM Authentication module that results in a Denial of Service (segfault).
CVE-2020-15701 1 Canonical 2 Apport, Ubuntu Linux 2024-09-16 5.5 Medium
An unhandled exception in check_ignored() in apport/report.py can be exploited by a local attacker to cause a denial of service. If the mtime attribute is a string value in apport-ignore.xml, it will trigger an unhandled exception, resulting in a crash. Fixed in 2.20.1-0ubuntu2.24, 2.20.9-0ubuntu7.16, 2.20.11-0ubuntu27.6.
CVE-2021-32555 1 Canonical 1 Ubuntu Linux 2024-09-16 7.3 High
It was discovered that read_file() in apport/hookutils.py would follow symbolic links or open FIFOs. When this function is used by the xorg-hwe-18.04 package apport hooks, it could expose private data to other local users.
CVE-2013-1064 1 Canonical 2 Apt-xapian-index, Ubuntu Linux 2024-09-16 N/A
apt-xapian-index before 0.45ubuntu2.1, 0.44ubuntu7.1, and 0.44ubuntu5.1 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, a related issue to CVE-2013-4288.
CVE-2019-11480 1 Canonical 1 C-kernel 2024-09-16 8.4 High
The pc-kernel snap build process hardcoded the --allow-insecure-repositories and --allow-unauthenticated apt options when creating the build chroot environment. This could allow an attacker who is able to perform a MITM attack between the build environment and the Ubuntu archive to install a malicious package within the build chroot. This issue affects pc-kernel versions prior to and including 2019-07-16
CVE-2019-15790 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2024-09-16 2.8 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-2018-9415 2 Canonical, Google 2 Ubuntu Linux, Android 2024-09-16 N/A
In driver_override_store and driver_override_show of bus.c, there is a possible double free due to improper locking. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android ID: A-69129004 References: Upstream kernel.
CVE-2017-14179 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2024-09-16 N/A
Apport before 2.13 does not properly handle crashes originating from a PID namespace allowing local users to create certain files as root which an attacker could leverage to perform a denial of service via resource exhaustion, possibly gain root privileges, or escape from containers.
CVE-2017-14180 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2024-09-16 N/A
Apport 2.13 through 2.20.7 does not properly handle crashes originating from a PID namespace allowing local users to create certain files as root which an attacker could leverage to perform a denial of service via resource exhaustion or possibly gain root privileges, a different vulnerability than CVE-2017-14179.
CVE-2016-9600 3 Canonical, Jasper Project, Redhat 9 Ubuntu Linux, Jasper, Enterprise Linux and 6 more 2024-09-16 N/A
JasPer before version 2.0.10 is vulnerable to a null pointer dereference was found in the decoded creation of JPEG 2000 image files. A specially crafted file could cause an application using JasPer to crash.
