Ubuntu Security Notice USN-1527-1
August 10, 2012

expat vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

Expat could be made to cause a denial of service by consuming excessive CPU
and memory resources.

Software Description:
- expat: XML parsing C library - example application

Details:

It was discovered that Expat computed hash values without restricting the
ability to trigger hash collisions predictably. If a user or application linked
against Expat were tricked into opening a crafted XML file, an attacker could
cause a denial of service by consuming excessive CPU resources. (CVE-2012-0876)

Tim Boddy discovered that Expat did not properly handle memory reallocation
when processing XML files. If a user or application linked against Expat were
tricked into opening a crafted XML file, an attacker could cause a denial of
service by consuming excessive memory resources. This issue only affected
Ubuntu 8.04 LTS, 10.04 LTS, 11.04 and 11.10. (CVE-2012-1148)
