"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."
