Description Jan Lieskovsky 2013-03-07 17:04:41 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2013-2488 to the following vulnerability:

The DTLS dissector in Wireshark 1.6.x before 1.6.14 and 1.8.x before 1.8.6 does not validate the fragment offset before invoking the reassembly state machine, which allows remote attackers to cause a denial of service (application crash) via a large offset value that triggers write access to an invalid memory location.
