Insight

TeX Live is an implementation of TeX. TeX takes a text file and a set of formatting commands as input, and creates a typesetter-independent DeVice Independent (DVI) file as output. The texlive packages provide a number of utilities, including dvips. 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) Red Hat would like to thank the Evince development team for reporting CVE-2010-2642. Upstream acknowledges Jon Larimer of IBM X-Force as the original reporter of CVE-2010-2642. All users of texlive are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
