Ubuntu 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : xmlrpc-c vulnerabilities (USN-1527-2)

medium Nessus Plugin ID 62036

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

USN-1527-1 fixed vulnerabilities in Expat. This update provides the corresponding updates for XML-RPC for C and C++. Both issues described in the original advisory affected XML-RPC for C and C++ in Ubuntu 10.04 LTS, 11.04, 11.10 and 12.04 LTS.

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libxmlrpc-core-c3 and / or libxmlrpc-core-c3-0 packages.
