Gentoo Linux Security Advisory 201701-57 - Multiple vulnerabilities have been discovered in T1Lib, the worst of which could lead to remote execution of arbitrary code. Versions less than 5.1.2-r1 are affected.
b2873c49c9fb6b6a50355619b845a09f6eee18b440a36822021f1f915877e044Mandriva Linux Security Advisory 2012-144 - Multiple vulnerabilities has been found and corrected in tetex. The Gfx::getPos function in the PDF parser in poppler, allows context-dependent attackers to cause a denial of service via unknown vectors that trigger an uninitialized pointer dereference. The FoFiType1::parse function in fofi/FoFiType1.cc in the PDF parser in poppler, allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via a PDF file with a crafted Type1 font that contains a negative array index, which bypasses input validation and which triggers memory corruption. Various other issues have also been addressed. The updated packages have been patched to correct these issues.
5c8b23cd2ecf83077e06d18f8f80cd038b4b0c331dd6a9baa869678d5a8dcadfRed Hat Security Advisory 2012-1201-01 - teTeX 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 file as output. teTeX embeds a copy of t1lib 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 files. If a specially-crafted font file was opened by teTeX, it could cause teTeX to crash or, potentially, execute arbitrary code with the privileges of the user running teTeX.
d3248156611725ad0fff7bd788cea1045887a17ec5ff1a6e89904341be92c76eSlackware Security Advisory - New t1lib packages are available for Slackware 12.1, 12.2, 13.0, 13.1, 13.37, and -current to fix security issues. These fixes include overflows, crashes, and pointer bugs.
aca91d3d6ff3435ba1461c911ecfeabf51d810fd120a10d94a1a06a0d8a10e46Red Hat Security Advisory 2012-0137-01 - 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 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 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.

Two heap-based buffer overflow flaws were found in the way t1lib processed Adobe Font Metrics 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. 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.

826cbdcd9ebdd1ede5d583faeba9ffd5a6efaea2feab949f5f4db2e314923ec2Mandriva Linux Security Advisory 2012-002 - t1lib 5.1.2 and earlier uses an invalid pointer in conjunction with a dereference operation, which allows remote attackers to execute arbitrary code via a specially crafted Type 1 font in a PDF document. The updated packages have been patched to correct this issue.
60428b231e6e685f90934eef256d10a1f276a4dc719c3d75122cf6e911385901Ubuntu Security Notice 1316-1 - Jonathan Brossard discovered that t1lib did not correctly handle certain malformed font files. If a user were tricked into using a specially crafted font file, a remote attacker could cause t1lib to crash or possibly execute arbitrary code with user privileges.
70fc8a23e9714c5972c4c937a393b4065ee9b324fc17ba3e3de0f2b5c50e3f77The Linux version of xpdf is linked against t1lib, which is vulnerable to multiple vulnerabilities including off by ones, integer overflows and heap corruptions. At least one of those is exploitable and allows arbitrary code to be executed on the target machine when opening a specially crafted pdf file.
