Scientific Linux Security Update : t1lib on SL6.x i386/x86_64 (20120124)

high Nessus Plugin ID 61226

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

The t1lib library allows you to rasterize bitmaps from PostScript Type 1 fonts.

Two heap-based buffer overflow flaws were found in the way t1lib processed Adobe Font Metrics (AFM) files. If a specially crafted font file was opened by an application linked against t1lib, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2010-2642, CVE-2011-0433)

An invalid pointer dereference flaw was found in t1lib. A specially crafted font file could, when opened, cause an application linked against t1lib to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2011-0764)

A use-after-free flaw was found in t1lib. A specially crafted font file could, when opened, cause an application linked against t1lib to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2011-1553)

An off-by-one flaw was found in t1lib. A specially crafted font file could, when opened, cause an application linked against t1lib to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2011-1554)

An out-of-bounds memory read flaw was found in t1lib. A specially crafted font file could, when opened, cause an application linked against t1lib to crash. (CVE-2011-1552)

All users of t1lib are advised to upgrade to these updated packages, which contain backported patches to correct these issues. All applications linked against t1lib must be restarted for this update to take effect.

Solution

Update the affected packages.
