Detailsinfo

A vulnerability, which was classified as critical, was found in Wireshark 1.8.0/1.8.1 (Packet Analyzer Software). This affects the function channelised_fill_sdh_g707_format of the file epan/dissectors/packet-erf.c of the component ERF Dissector. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in the channelised_fill_sdh_g707_format function in epan/dissectors/packet-erf.c in the ERF dissector in Wireshark 1.8.x before 1.8.2 allows remote attackers to execute arbitrary code via a large speed (aka rate) value.
