Description :

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)
