Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Chris Evans discovered that libxslt incorrectly handled generate-id XPath functions. If a user or automated system were tricked into processing a specially crafted XSLT document, a remote attacker could obtain potentially sensitive information. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS and Ubuntu 11.04. (CVE-2011-1202)

It was discovered that libxslt incorrectly parsed certain patterns. If a user or automated system were tricked into processing a specially crafted XSLT document, a remote attacker could cause libxslt to crash, causing a denial of service. (CVE-2011-3970)

Nicholas Gregoire discovered that libxslt incorrectly handled unexpected DTD nodes. If a user or automated system were tricked into processing a specially crafted XSLT document, a remote attacker could cause libxslt to crash, causing a denial of service. (CVE-2012-2825)

If a user or automated system were tricked into processing a specially crafted XSLT document, a remote attacker could cause libxslt to crash, causing a denial of service. (CVE-2012-2870)

Nicholas Gregoire discovered that libxslt incorrectly handled certain transforms. If a user or automated system were tricked into processing a specially crafted XSLT document, a remote attacker could cause libxslt to crash, causing a denial of service, or possibly execute arbitrary code. (CVE-2012-2871)

Cris Neckar discovered that libxslt incorrectly managed memory. If a user or automated system were tricked into processing a specially crafted XSLT document, a remote attacker could cause libxslt to crash, causing a denial of service, or possibly execute arbitrary code.
(CVE-2012-2893).

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.
