Amazon Linux AMI Security Advisory: ALAS-2012-40
Advisory Release Date: 2014-09-14 15:15 Pacific
Severity: Medium

Issue Overview:

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 )
