Description
This security bulletin contains information about 1 security vulnerability.
1) Input validation error (CVE-ID: CVE-2013-2488)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
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.
Remediation
Install update from vendor's website.
