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)
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 t1lib are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. All applications linked
against t1lib must be restarted for this update to take effect.");
