An issue has been found in luajit, a just in time compiler for Lua. An out-of-bounds read could happen because __gc handler frame traversal is mishandled (CVE-2020-15890). References:
Chrony's method of opening its PID file could allow a compromised chrony user account to overwrite files in certain parts of the filesystem with chrony's PID, using a symlink attack (CVE-2020-14367). References:
The Server-Server protocol implementation in ngIRCd before 26~rc2 allows an out-of-bounds access, as demonstrated by the IRC_NJOIN() function. (CVE-2020-14148) References:
Fix potential XSS issue in HTML editor of the identity signature input Fix cross-site scripting (XSS) via HTML messages with malicious svg content [CVE-2020-16145] Fix cross-site scripting (XSS) via HTML messages with malicious math content References:
Integer overflow due to missing input sanitation in rdpegfx channel. The input rectangles from the server are not checked against local surface coordinates and blindly accepted. A malicious server can send data that will crash the client later on (invalid length arguments to a memcpy) (CVE-2020-15103).
The jas_matrix_bindsub function in jas_seq.c in JasPer 2.0.10 allows remote attackers to cause a denial of service (invalid read) via a crafted image (CVE-2017-6851). Heap-based buffer overflow in the jpc_dec_decodepkt function in jpc_t2dec.c in
Open-iSCSI rtslib-fb through 2.1.72 has weak permissions for /etc/target/saveconfig.json because shutil.copyfile (instead of shutil.copy) is used and thus permissions are not preserved upon editing. An adversary with prior access to /etc/target/saveconfig.json could access a later version, resulting in a loss of integrity depending on their permission settings
Allocation for pixmap data in AllocatePixmap() does not initialize the memory in xserver, it leads to leak uninitialize heap memory to clients. When the X server runs with elevated privileges. This flaw can lead to ASLR bypass, which when combined with other flaws (known/unknown) could lead to lead to privilege elevation in the client (CVE-2020-14347).
