Amazon Linux AMI : texlive (ALAS-2012-48)

High Nessus Plugin ID 69655

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

TeX Live embeds a copy of t1lib. The t1lib library allows you to rasterize bitmaps from PostScript Type 1 fonts. The following issues affect t1lib code :

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 a TeX Live utility, it could cause the utility to crash or, potentially, execute arbitrary code with the privileges of the user running the utility. (CVE-2010-2642 , CVE-2011-0433)

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

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

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

An out-of-bounds memory read flaw was found in t1lib. A specially crafted font file could, when opened, cause a TeX Live utility to crash. (CVE-2011-1552)

Solution
