Several vulnerabilities have been discovered in the FreeType font library. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2010-1797     Multiple stack-based buffer overflows in the     cff_decoder_parse_charstrings function in the CFF Type2     CharStrings interpreter in cff/cffgload.c in FreeType     allow remote attackers to execute arbitrary code or     cause a denial of service (memory corruption) via     crafted CFF opcodes in embedded fonts in a PDF document,     as demonstrated by JailbreakMe.

  - CVE-2010-2541     Buffer overflow in ftmulti.c in the ftmulti demo program     in FreeType allows remote attackers to cause a denial of     service (application crash) or possibly execute     arbitrary code via a crafted font file.

  - CVE-2010-2805     The FT_Stream_EnterFrame function in base/ftstream.c in     FreeType does not properly validate certain position     values, which allows remote attackers to cause a denial     of service (application crash) or possibly execute     arbitrary code via a crafted font file

  - CVE-2010-2806     Array index error in the t42_parse_sfnts function in     type42/t42parse.c in FreeType allows remote attackers to     cause a denial of service (application crash) or     possibly execute arbitrary code via negative size values     for certain strings in FontType42 font files, leading to     a heap-based buffer overflow.

  - CVE-2010-2807     FreeType uses incorrect integer data types during bounds     checking, which allows remote attackers to cause a     denial of service (application crash) or possibly     execute arbitrary code via a crafted font file.

  - CVE-2010-2808     Buffer overflow in the Mac_Read_POST_Resource function     in base/ftobjs.c in FreeType allows remote attackers to     cause a denial of service (memory corruption and     application crash) or possibly execute arbitrary code     via a crafted Adobe Type 1 Mac Font File (aka LWFN)     font.

  - CVE-2010-3053     bdf/bdflib.c in FreeType allows remote attackers to     cause a denial of service (application crash) via a     crafted BDF font file, related to an attempted     modification of a value in a static string.

Multiple vulnerabilities has been found and corrected in freetype2 :

The FT_Stream_EnterFrame function in base/ftstream.c in FreeType before 2.4.2 does not properly validate certain position values, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file (CVE-2010-2805).

Array index error in the t42_parse_sfnts function in type42/t42parse.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via negative size values for certain strings in FontType42 font files, leading to a heap-based buffer overflow (CVE-2010-2806).

FreeType before 2.4.2 uses incorrect integer data types during bounds checking, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file (CVE-2010-2807).

Buffer overflow in the Mac_Read_POST_Resource function in base/ftobjs.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted Adobe Type 1 Mac Font File (aka LWFN) font (CVE-2010-2808).

bdf/bdflib.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service (application crash) via a crafted BDF font file, related to an attempted modification of a value in a static string (CVE-2010-3053).

The updated packages have been patched to correct these issues.

The updated packages have been patched to correct these issues.

It was discovered that FreeType 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 FreeType to crash or possibly execute arbitrary code with user privileges.
