| Description: | Summary:
The remote host is missing an update for the Debian 'freetype' package(s) announced via the DSA-2105-1 advisory.
Vulnerability Insight:
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
