Synopsis :

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

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 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)
