Categoría:	Mageia Linux Local Security Checks
Título:	Mageia: Security Advisory (MGASA-2016-0187)
Resumen:	The remote host is missing an update for the 'libxml2' package(s) announced via the MGASA-2016-0187 advisory.
Descripción:	Summary: The remote host is missing an update for the 'libxml2' package(s) announced via the MGASA-2016-0187 advisory. Vulnerability Insight: When running in recovery mode, certain invalid XML documents would trigger an infinite recursion in libxml2 that ran until all stack space was exhausted. This vulnerability could have been used to facilitate a denial-of-sevice attack (CVE-2016-3627). libxml2 limits the number of recursions an XML document can contain so to protect against the 'Billion Laughs' denial-of-service attack. Unfortunately, the underlying counter was not incremented properly in all necessary locations. Therefore, specially crafted XML documents could exhaust all available stack space and crash the XML parser without running into the recursion limit (CVE-2016-3705). Affected Software/OS: 'libxml2' package(s) on Mageia 5. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
