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.
CVE-2013-1067 1 Canonical 1 Ubuntu Linux 2024-09-16 N/A
Apport 2.12.5 and earlier uses weak permissions for core dump files created by setuid binaries, which allows local users to obtain sensitive information by reading the file.
CVE-2020-8617 6 Canonical, Debian, Fedoraproject and 3 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2024-09-16 7.5 High
Using a specially-crafted message, an attacker may potentially cause a BIND server to reach an inconsistent state if the attacker knows (or successfully guesses) the name of a TSIG key used by the server. Since BIND, by default, configures a local session key even on servers whose configuration does not otherwise make use of it, almost all current BIND servers are vulnerable. In releases of BIND dating from March 2018 and after, an assertion check in tsig.c detects this inconsistent state and deliberately exits. Prior to the introduction of the check the server would continue operating in an inconsistent state, with potentially harmful results.
CVE-2018-8785 2 Canonical, Freerdp 2 Ubuntu Linux, Freerdp 2024-09-16 9.8 Critical
FreeRDP prior to version 2.0.0-rc4 contains a Heap-Based Buffer Overflow in function zgfx_decompress() that results in a memory corruption and probably even a remote code execution.
CVE-2017-0901 4 Canonical, Debian, Redhat and 1 more 11 Ubuntu Linux, Debian Linux, Enterprise Linux and 8 more 2024-09-16 N/A
RubyGems version 2.6.12 and earlier fails to validate specification names, allowing a maliciously crafted gem to potentially overwrite any file on the filesystem.
CVE-2021-3489 3 Canonical, Linux, Redhat 3 Ubuntu Linux, Linux Kernel, Enterprise Linux 2024-09-16 7.8 High
The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee ("bpf, ringbuf: Deny reserve of buffers larger than ringbuf") (v5.13-rc4) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced via 457f44363a88 ("bpf: Implement BPF ring buffer and verifier support for it") (v5.8-rc1).
CVE-2021-32551 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 openjdk-15 package apport hooks, it could expose private data to other local users.
CVE-2017-15130 3 Canonical, Debian, Dovecot 3 Ubuntu Linux, Debian Linux, Dovecot 2024-09-16 N/A
A denial of service flaw was found in dovecot before 2.2.34. An attacker able to generate random SNI server names could exploit TLS SNI configuration lookups, leading to excessive memory usage and the process to restart.
CVE-2017-2888 3 Canonical, Debian, Libsdl 3 Ubuntu Linux, Debian Linux, Simple Directmedia Layer 2024-09-16 8.8 High
An exploitable integer overflow vulnerability exists when creating a new RGB Surface in SDL 2.0.5. A specially crafted file can cause an integer overflow resulting in too little memory being allocated which can lead to a buffer overflow and potential code execution. An attacker can provide a specially crafted image file to trigger this vulnerability.
CVE-2018-5378 3 Canonical, Debian, Quagga 3 Ubuntu Linux, Debian Linux, Quagga 2024-09-16 N/A
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-2018-8787 4 Canonical, Debian, Freerdp and 1 more 10 Ubuntu Linux, Debian Linux, Freerdp and 7 more 2024-09-16 9.8 Critical
FreeRDP prior to version 2.0.0-rc4 contains an Integer Overflow that leads to a Heap-Based Buffer Overflow in function gdi_Bitmap_Decompress() and results in a memory corruption and probably even a remote code execution.
CVE-2013-2145 3 Canonical, Opensuse, Perlmonks 3 Ubuntu Linux, Opensuse, Module\ 2024-09-16 N/A
The cpansign verify functionality in the Module::Signature module before 0.72 for Perl allows attackers to bypass the signature check and execute arbitrary code via a SIGNATURE file with a "special unknown cipher" that references an untrusted module in Digest/.
CVE-2012-2317 2 Canonical, Debian 4 Php5, Ubuntu Linux, Debian Linux and 1 more 2024-09-16 N/A
The Debian php_crypt_revamped.patch patch for PHP 5.3.x, as used in the php5 package before 5.3.3-7+squeeze4 in Debian GNU/Linux squeeze, the php5 package before 5.3.2-1ubuntu4.17 in Ubuntu 10.04 LTS, and the php5 package before 5.3.5-1ubuntu7.10 in Ubuntu 11.04, does not properly handle an empty salt string, which might allow remote attackers to bypass authentication by leveraging an application that relies on the PHP crypt function to choose a salt for password hashing.
CVE-2013-1056 1 Canonical 1 Ubuntu Linux 2024-09-16 N/A
X.org X server 1.13.3 and earlier, when not run as root, allows local users to cause a denial of service (crash) or possibly gain privileges via vectors involving cached xkb files.
CVE-2019-15794 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2024-09-16 7.1 High
Overlayfs in the Linux kernel and shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, both replace vma->vm_file in their mmap handlers. On error the original value is not restored, and the reference is put for the file to which vm_file points. On upstream kernels this is not an issue, as no callers dereference vm_file following after call_mmap() returns an error. However, the aufs patchs change mmap_region() to replace the fput() using a local variable with vma_fput(), which will fput() vm_file, leading to a refcount underflow.
CVE-2018-6553 3 Canonical, Cups, Debian 3 Ubuntu Linux, Cups, Debian Linux 2024-09-16 N/A
The CUPS AppArmor profile incorrectly confined the dnssd backend due to use of hard links. A local attacker could possibly use this issue to escape confinement. This flaw affects versions prior to 2.2.7-1ubuntu2.1 in Ubuntu 18.04 LTS, prior to 2.2.4-7ubuntu3.1 in Ubuntu 17.10, prior to 2.1.3-4ubuntu0.5 in Ubuntu 16.04 LTS, and prior to 1.7.2-0ubuntu1.10 in Ubuntu 14.04 LTS.
