CVE-2024-2955: CWE-762: Mismatched Memory Management Routines in Wireshark Foundation Wireshark
T.38 dissector crash in Wireshark 4.2.0 to 4.0.3 and 4.0.0 to 4.0.13 allows denial of service via packet injection or crafted capture file
AI Analysis
Technical Summary
The vulnerability CVE-2024-2955 affects Wireshark versions 4.0.0 through 4.0.13 and 4.2.0. It arises from mismatched memory management routines in the T.38 protocol dissector, leading to a crash when handling specially crafted packets or capture files. This causes a denial of service condition. The CVSS 3.1 base score is 7.8, reflecting high severity with local attack vector, low attack complexity, no privileges required, user interaction needed, and impacts on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation results in a denial of service by crashing the Wireshark application, potentially disrupting network traffic analysis or forensic activities. The impact affects confidentiality, integrity, and availability as indicated by the CVSS vector. There are no reports of active exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the Wireshark Foundation's official advisory for current remediation guidance. Until a patch is available, users should avoid opening untrusted capture files or processing untrusted T.38 packets to mitigate risk.
