                 CVE-2010-2807 CVE-2010-2808 CVE-2010-3053


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.


For the stable distribution (lenny), these problems have been fixed in
version 2.3.7-2+lenny3

For the unstable distribution (sid) and the testing distribution
(squeeze), these problems have been fixed in version 2.4.2-1


We recommend that you upgrade your freetype package.
