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

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)
