CVE-2022-3437

Name of the Vulnerable Software and Affected Versions Samba (affected versions not specified)

Description A heap-based buffer overflow issue was found in the GSSAPI unwrap des() and unwrap des3() routines of Heimdal, which is part of the Samba network interaction program. This issue allows a remote user to send specially crafted malicious data, possibly resulting in a denial of service (DoS) attack. The DES and Triple-DES decryption routines in the Heimdal GSSAPI library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a maliciously small packet.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
