Synopsis
The remote FreeBSD host is missing a security-related update.Description
Secunia reports :- An integer overflow error exists in the processing of PFB font files. This can be exploited to cause a heap-based buffer overflow via a PFB file containing a specially crafted 'Private' dictionary table.
- An error in the processing of PFB font files can be exploited to trigger the 'free()' of memory areas that are not allocated on the heap.
- An off-by-one error exists in the processing of PFB font files. This can be exploited to cause a one-byte heap-based buffer overflow via a specially crafted PFB file.
- An off-by-one error exists in the implementation of the 'SHC' instruction while processing TTF files. This can be exploited to cause a one-byte heap-based buffer overflow via a specially crafted TTF file.
Successful exploitation of the vulnerabilities may allow execution of arbitrary code.
