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. 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.
