Last modified

CVE-2013-2488 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.83% chance of exploitation in the next 30 days.
