SynopsisThe remote Debian host is missing a security-related update.
DescriptionSeveral 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 arbitrary 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.
SolutionUpgrade the freetype package.
For the stable distribution (etch), these problems have been fixed in version 2.2.1-5+etch3.
