TITLE

libxml2 of parser.c of xmlParseElementDecl Service disruption in functions (DoS) Vulnerabilities

DESCRIPTION

The xmlParseElementDecl function in parser.c in libxml2 before 2.9.4 allows context-dependent attackers to cause a denial of service (heap-based buffer underread and application crash) via a crafted file, involving xmlParseName. Libxml2 is prone to a remote denial-of-service vulnerability. An attacker may exploit this issue to cause a denial-of-service condition. Given the nature of this issue, attackers may also be able to execute arbitrary code, but this has not been confirmed. It supports multiple encoding formats, XPath analysis, Well-formed and valid verification, etc. From: Marc Deslauriers <marc.deslauriers@canonical.com> Reply-To: Ubuntu Security <security@ubuntu.com> To: ubuntu-security-announce@lists.ubuntu.com Message-ID: <5755B7E3.5040103@canonical.com> Subject: [USN-2994-1] libxml2 vulnerabilities ============================================================================ Ubuntu Security Notice USN-2994-1 June 06, 2016 libxml2 vulnerabilities ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS - Ubuntu 15.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in libxml2. Software Description: - libxml2: GNOME XML library Details: It was discovered that libxml2 incorrectly handled certain malformed documents.
