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.
