  script_tag(name:"insight", value:"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.");
