Oracle Solaris Third-Party Patch Update : libexpat (multiple_resource_management_error_vulnerabilities)

medium Nessus Plugin ID 80669

Language:

Synopsis

The remote Solaris system is missing a security patch for third-party software.

Description

The remote Solaris system is missing necessary patches to address security updates :

 - The XML parser (xmlparse.c) in expat before 2.1.0 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via an XML file with many identifiers with the same value. (CVE-2012-0876)

 - Memory leak in the poolGrow function in expat/lib/xmlparse.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (memory consumption) via a large number of crafted XML files that cause improperly-handled reallocation failures when expanding entities. (CVE-2012-1148)

Solution

Upgrade to Solaris 11/11 SRU 11.4.
