A flaw was found in OpenSSL. It is possible to trigger an infinite loop by crafting a certificate that has invalid elliptic curve parameters. Since certificate parsing happens before verification of the certificate signature, any process that parses an externally supplied certificate may be subject to a denial of service attack.
AMD. A buffer overflow issue was addressed with improved memory handling.
A carefully crafted request body can cause a read to a random memory area which could cause the process to crash. This issue affects Apache HTTP Server 2.4.52 and earlier.
A flaw was found in libxml2. Parsing a XML document with the XMLPARSEHUGE option enabled can result in an integer overflow because safety checks were missing in some functions. Also, the xmlParseEntityValue function didn't have any length limitation.
A flaw was found in libxml2. When a reference cycle is detected in the XML entity cleanup function the XML entity data can be stored in a dictionary. In this case, the dictionary becomes corrupted resulting in logic errors, including memory errors like double free.
A flaw was found in libxml2. A call to the xmlGetID function can return a pointer already freed when parsing an XML document with the XMLPARSEDTDVALID option and without the XMLPARSENOENT option, resulting in a use-after-free issue.
A vulnerability was found in libpcre in PCRE before 8.43 allows a subject buffer over-read in JIT when UTF is disabled, and \X or \R has more than one fixed quantifier, a related issue to CVE-2019-20454.

A flaw was found in rubygem-json. While parsing certain JSON documents, the json gem (including the one bundled with Ruby) can be coerced into creating arbitrary objects in the target system. This is the same issue as CVE-2013-0269.

ActionKit. An input validation issue was addressed with improved input validation.
A heap-based buffer overflow was found in the way sudo parses command line arguments.
As per the researcher this vulnerability:
- is exploitable by any local user (normal users and system users, sudoers and non-sudoers), without authentication (i.e., the attacker does not need to know the user's password);
- was introduced in July 2011 (commit 8255ed69), and affects all legacy versions from 1.8.2 to 1.8.31p2 and all stable versions from 1.9.0 to 1.9.5p1, in their default configuration.
This could lead to privilege escalation.
