CVE-2015-3809
First published: Tue May 26 2015(Updated: )
The dissect_lbmr_pser function in epan/dissectors/packet-lbmr.c in the LBMR dissector in Wireshark 1.12.x before 1.12.5 does not properly track the current offset, which allows remote attackers to cause a denial of service (infinite loop) via a crafted packet.
