epan/dissectors/packet-h225.c in the H.225 dissector in Wireshark 2.x before 2.0.6 calls snprintf with one of its input buffers as the output buffer, which allows remote attackers to cause a denial of service (copy overlap and application crash) via a crafted packet.
AnalysisAI
epan/dissectors/packet-h225.c in the H.225 dissector in Wireshark 2.x before 2.0.6 calls snprintf with one of its input buffers as the output buffer, which allows remote attackers to cause a denial. Rated medium severity (CVSS 5.9), this vulnerability is remotely exploitable, no authentication required. This Buffer Overflow vulnerability could allow attackers to corrupt memory to execute arbitrary code or crash the application.
Technical ContextAI
This vulnerability is classified as Buffer Overflow (CWE-119), which allows attackers to corrupt memory to execute arbitrary code or crash the application. epan/dissectors/packet-h225.c in the H.225 dissector in Wireshark 2.x before 2.0.6 calls snprintf with one of its input buffers as the output buffer, which allows remote attackers to cause a denial of service (copy overlap and application crash) via a crafted packet. Affected products include: Wireshark, Debian Debian Linux. Version information: before 2.0.6.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Use memory-safe languages or bounds-checking. Enable ASLR, DEP/NX, stack canaries. Use safe string functions.
