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.

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.

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.
b811af510a4450cdfa8f0478df6a3e2ec1303502c4a2f0b164a2de49291aa9d1Ubuntu Security Notice 1347-1 - It was discovered that Evince did not properly parse AFM font files when processing DVI files. If a user were tricked into opening a specially crafted DVI file, an attacker could cause Evince to crash or potentially execute arbitrary code with the privileges of the user invoking the program. In the default installation, attackers would be isolated by the Evince AppArmor profile. Various other issues were also addressed.

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.

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. 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. Various other issues were also addressed.

826cbdcd9ebdd1ede5d583faeba9ffd5a6efaea2feab949f5f4db2e314923ec2Mandriva Linux Security Advisory 2012-004 - Multiple vulnerabilities has been found and corrected in t1lib. A heap-based buffer overflow flaw was found in the way AFM font file parser, used for rendering of DVI files, in GNOME evince document viewer and other products, processed line tokens from the given input stream. A remote attacker could provide a DVI file, with embedded specially-crafted font file, and trick the local user to open it with an application using the AFM font parser, leading to that particular application crash or, potentially, arbitrary code execution with the privileges of the user running the application. Various other issues were also addressed.
