Mandriva Linux Security Advisory 2010-157 - 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. 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 or possibly execute arbitrary code via negative size values for certain strings in FontType42 font files, leading to a heap-based buffer overflow. FreeType before 2.4.2 uses incorrect integer data types during bounds checking, which allows remote attackers to cause a denial of service or possibly execute arbitrary code via a crafted font file. 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 or possibly execute arbitrary code via a crafted Adobe Type 1 Mac Font File font. bdf/bdflib.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service via a crafted BDF font file, related to an attempted modification of a value in a static string. The updated packages have been patched to correct these issues.

Package : freetype2
Date : August 22, 2010
Affected: 2010.0, 2010.1
_______________________________________________________________________

Problem Description:

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.
