Detailsinfo

A vulnerability was found in tcpdump 3.9.5 (Packet Analyzer Software). It has been rated as critical. This issue affects the function parse_elements of the file print-802_11.c. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Off-by-one buffer overflow in the parse_elements function in the 802.11 printer code (print-802_11.c) for tcpdump 3.9.5 and earlier allows remote attackers to cause a denial of service (crash) via a crafted 802.11 frame. NOTE: this was originally referred to as heap-based, but it might be stack-based.
