CVE Id(s) : CVE-2008-1806 CVE-2008-1807 CVE-2008-1808
Several local vulnerabilities have been discovered in freetype,
a FreeType 2 font engine, which could allow the execution of arbitrary
code.
The Common Vulnerabilities and Exposures project identifies the
following problems:
CVE-2008-1806
An integer overflow allows context-dependent attackers to execute
arbitrary code via a crafted set of values within the Private
dictionary table in a Printer Font Binary (PFB) file.
CVE-2008-1807
The handling of an invalid "number of axes" field in the PFB file could
trigger the freeing of aribtrary memory locations, leading to
memory corruption.
CVE-2008-1808
Multiple off-by-one errors allowed the execution of arbitrary code
via malformed tables in PFB files, or invalid SHC instructions in
TTF files.
For the stable distribution (etch), these problems have been fixed in version 2.2.1-5+etch3.
For the unstable distribution (sid), these problems have been fixed in
version 2.3.6-1.
We recommend that you upgrade your freetype package.
