Description Laura Pardo 2018-02-08 18:37:49 UTC 
The netmonrec_comment_destroy function in wiretap/netmon.c in Wireshark through 2.4.4 performs a free operation on an uninitialized memory address, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.
