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.
