t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6, teTeX, and other products, uses an invalid pointer in conjunction with a dereference operation, which allows remote attackers to execute arbitrary code via a crafted Type 1 font in a PDF document, as demonstrated by testz.2184122398.pdf.

The remote host is affected by the vulnerability described in GLSA-201701-57 (T1Lib: : Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in T1Lib. Please review       the CVE identifiers referenced below for details.
  Impact :

    Remote attackers, by coercing users to process specially crafted AFM       font or PDF file, could cause a Denial of Service condition or execute       arbitrary code.
  Workaround :

    There is no known workaround at this time.

Specially crafted type1 fonts could cause memory corruptions in t1lib

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 (AFM) 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. (CVE-2010-2642 , CVE-2011-0433)

An invalid pointer dereference flaw was found in t1lib. A specially crafted font file could, when opened, cause a TeX Live utility to crash or, potentially, execute arbitrary code with the privileges of the user running the utility. (CVE-2011-0764)

This update fixes several security flaws in t1lib (flaws in AFM parser and when handling specially crafted Type1 fonts).

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several vulnerabilities were discovered in t1lib, a Postscript Type 1 font rasterizer library, some of which might lead to code execution through the opening of files embedding bad fonts.

  - CVE-2010-2642     A heap-based buffer overflow in the AFM font metrics     parser potentially leads to the execution of arbitrary     code.

  - CVE-2011-0433     Another heap-based buffer overflow in the AFM font     metrics parser potentially leads to the execution of     arbitrary code.

  - CVE-2011-0764     An invalid pointer dereference allows execution of     arbitrary code using crafted Type 1 fonts.

  - CVE-2011-1552     Another invalid pointer dereference results in an     application crash, triggered by crafted Type 1 fonts.

  - CVE-2011-1553     A use-after-free vulnerability results in an application     crash, triggered by crafted Type 1 fonts.

  - CVE-2011-1554     An off-by-one error results in an invalid memory read     and application crash, triggered by crafted Type 1     fonts.

A vulnerability has been found and corrected in t1lib :

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 (CVE-2011-0764).

The updated packages have been patched to correct this issue.

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.
