Use-after-free vulnerability in t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6, teTeX, and other products, allows remote attackers to cause a denial of service (application crash) via a PDF document containing a crafted Type 1 font that triggers an invalid memory write, a different vulnerability than CVE-2011-0764.

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.

Jon Larimer discovered that t1lib did not properly parse AFM fonts. 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. (CVE-2010-2642, CVE-2011-0433)

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. (CVE-2011-1552, CVE-2011-1553, CVE-2011-1554).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu 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.

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. Different vulnerability than CVE-2010-2642 (CVE-2011-0433).

t1lib 5.1.2 and earlier reads from invalid memory locations, which allows remote attackers to cause a denial of service (application crash) via a crafted Type 1 font in a PDF document, a different vulnerability than CVE-2011-0764 (CVE-2011-1552).

Use-after-free vulnerability in t1lib 5.1.2 and earlier allows remote attackers to cause a denial of service (application crash) via a PDF document containing a crafted Type 1 font that triggers an invalid memory write, a different vulnerability than CVE-2011-0764 (CVE-2011-1553).
