Package : freetype
Vulnerability : several
Problem type : local(remote)
Debian-specific: no
CVE Id(s) : CVE-2010-1797 CVE-2010-2541 CVE-2010-2805 CVE-2010-2806
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.

Upgrade instructions
- --------------------

wget url
