Ixia IxVeriWave and Vector Informatik BLF file parser crashes in 4.6.0 to 4.6.7 allows denial of service on Windows
A flaw was found in the Ixia IxVeriWave and Vector Informatik BLF file parsers in Wireshark. This issue occurs when malformed packets are decoded from a packet capture file, causing an out-of-bounds write, resulting in a denial of service.
Statement: This issue will cause a crash in Wireshark, with no evidence of arbitrary code execution. This vulnerability can only be exploited when a malformed packet capture file is processed on a Windows system. Due to these reasons, this flaw has been rated with a moderate severity.
