Ubuntu 8.04 LTS / 9.10 / 10.04 LTS / 10.10 : pango1.0 vulnerabilities (USN-1082-1)

High Nessus Plugin ID 52529

Synopsis

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

Description

Marc Schoenefeld discovered that Pango incorrectly handled certain Glyph Definition (GDEF) tables. If a user were tricked into displaying text with a specially crafted font, an attacker could cause Pango to crash, resulting in a denial of service. This issue only affected Ubuntu 8.04 LTS and 9.10. (CVE-2010-0421)

Dan Rosenberg discovered that Pango incorrectly handled certain FT_Bitmap objects. If a user were tricked into displaying text with a specially- crafted font, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. The default compiler options for affected releases should reduce the vulnerability to a denial of service. (CVE-2011-0020)

It was discovered that Pango incorrectly handled certain memory reallocation failures. If a user were tricked into displaying text in a way that would cause a reallocation failure, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. This issue only affected Ubuntu 9.10, 10.04 LTS and 10.10. (CVE-2011-0064).

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.
