The SMB protocol decoder in tcpdump version 4.99.3 can perform an out-of-bounds write when decoding a crafted network packet.
AnalysisAI
The SMB protocol decoder in tcpdump version 4.99.3 can perform an out-of-bounds write when decoding a crafted network packet. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. The SMB protocol decoder in tcpdump version 4.99.3 can perform an out-of-bounds write when decoding a crafted network packet. Affected products include: Tcpdump. Version information: version 4.99.3.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
