CVE-2016-2530: Buffer Overflow

Published Feb 28, 2016

Updated

The dissctrslipaccessmsg function in epan/dissectors/packet-rsl.c in the RSL dissector in Wireshark 1.12.x before 1.12.10 and 2.0.x before 2.0.2 mishandles the case of an unrecognized TLV type, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted packet, a different vulnerability than CVE-2016-2531.
