CVE-2022-3437 (GCVE-0-2022-3437)

Vulnerability from cvelistv5 – Published: 2023-01-12 00:00 – Updated: 2024-10-28 18:59
VLAI
Summary
A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and unwrap_des3() routines of Heimdal. 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. This flaw allows a remote user to send specially crafted malicious data to the application, possibly resulting in a denial of service (DoS) attack.
