Multiple heap-based buffer overflow vulnerabilities in the modpow function in PuTTYID: oval:org.secpod.oval:def:16582 | Date: (C)2014-01-23 (M)2023-03-24 |
Class: VULNERABILITY | Family: windows |
The host is installed with PuTTY before 0.55 and is prone to multiple heap-based buffer overflow vulnerabilities. The flaws are present in the application, which fails to properly handle an SSH2 packet with a base argument that is larger than the mod argument, which causes the modpow function to write memory before the beginning of its buffer, and (2) remote malicious servers to cause a denial of service (client crash). Successful exploitation could allow remote attackers to execute arbitrary code.
