SUSE SLED12 / SLES12 Security Update : expat (SUSE-SU-2017:0424-1)

High Nessus Plugin ID 97080


The remote SUSE host is missing one or more security updates.


This update for expat fixes the following security issues :

- CVE-2012-6702: Expat, when used in a parser that has not called XML_SetHashSalt or passed it a seed of 0, made it easier for context-dependent attackers to defeat cryptographic protection mechanisms via vectors involving use of the srand function. (bsc#983215)

- CVE-2016-5300: The XML parser in Expat did not use sufficient entropy for hash initialization, which allowed context-dependent attackers to cause a denial of service (CPU consumption) via crafted identifiers in an XML document. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-0876. (bsc#983216)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
