Ethereal uses the PCRE regular expression library. Security vulnerabilities have been discovered in older versions of this library. The Windows installer now ships with PCRE 6.3, which fixes these vulnerabilities.
CVE: CAN-2005-2491

Impact:

It may be possible to make Ethereal crash, use up available memory, or run arbitrary code by injecting a purposefully malformed packet onto the wire or by convincing someone to read a malformed packet trace file.

Resolution:

Upgrade to 0.10.13. Due to the severity and scope of the defects that have been discovered, no workaround is available.
