If a user saved passwords before Thunderbird 60 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Thunderbird 60. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations.

json-c could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow and out-of-bounds write. By persuading a victim to run a specially crafted file, an attacker could exploit this vulnerability to execute arbitrary code on the system.

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 getpidinfo() 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.addprocenviron 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.

A flaw was found in the way haproxy processed certain HTTP/2 request packets. An attacker could send crafted HTTP/2 request packets which cause memory corruption, leading to a crash or potential remote arbitrary code execution with the permissions of the user running haproxy.

ImageMagick 7.0.1-0 to 7.0.8-54 Q16 allows Division by Zero in RemoveDuplicateLayers in MagickCore/layer.c.

An issue was discovered in buttonopen in login/logind-button.c in systemd before 243. When executing the udevadm trigger command, a memory leak may occur.

A code execution vulnerability exists in the directory rehashing functionality of E2fsprogs e2fsck 1.45.4. A specially crafted ext4 directory can cause an out-of-bounds write on the stack, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability.

A heap-based buffer overflow was found in the NSCEncryptUpdate() function in Mozilla nss. A remote attacker could trigger this flaw via SRTP encrypt or decrypt operations, to execute arbitrary code with the permissions of the user running the application (compiled with nss). While the attack complexity is high, the impact to confidentiality, integrity, and availability are high as well.

Apport creates a world writable lock file with root ownership in the world writable /var/lock/apport directory. If the apport/ directory does not exist (this is not uncommon as /var/lock is a tmpfs), it will create the directory, otherwise it will simply continue execution using the existing directory. This allows for a symlink attack if an attacker were to create a symlink at /var/lock/apport, changing apport's lock file location. This file could then be used to escalate privileges, for example. Fixed in versions 2.20.1-0ubuntu2.23, 2.20.9-0ubuntu7.14, 2.20.11-0ubuntu8.8 and 2.20.11-0ubuntu22.

In FreeRDP after 1.0 and before 2.0.0, there is an out-of-bounds read. It only allows to abort a session. No data extraction is possible. This has been fixed in 2.0.0.

In FreeRDP greater than 1.2 and before 2.0.0, a double free in updatereadcachebitmapv3order crashes the client application if corrupted data from a manipulated server is parsed. This has been patched in 2.0.0.

In FreeRDP after 1.0 and before 2.0.0, there is an out-of-bound read in in updatereadbitmapdata that allows client memory to be read to an image buffer. The result displayed on screen as colour.

In FreeRDP after 1.1 and before 2.0.0, there is an out-of-bounds read in autodetectrecvbandwidthmeasureresults. A malicious server can extract up to 8 bytes of client memory with a manipulated message by providing a short input and reading the measurement result data. This has been patched in 2.0.0.

In FreeRDP after 1.0 and before 2.0.0, there is a stream out-of-bounds seek in updatereadsynchronize that could lead to a later out-of-bounds read.

In FreeRDP greater than 1.1 and before 2.0.0, there is an out-of-bounds read in updatereadiconinfo. It allows reading a attacker-defined amount of client memory (32bit unsigned -> 4GB) to an intermediate buffer. This can be used to crash the client or store information for later retrieval. This has been patched in 2.0.0.

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.

A memory leak in the cryptoreportstat() function in crypto/cryptouserstat.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering cryptoreportstatalg() failures, aka CID-c03b04dcdba1.
