PuTTY < 0.64 Multiple Information Disclosure Vulnerabilities
Medium Nessus Plugin ID 81669
SynopsisThe remote Windows host has an SSH client that is affected by multiple information disclosure vulnerabilities.
DescriptionThe remote host has a version of PuTTY installed that is prior to 0.64. It is, therefore, affected by multiple vulnerabilities :
- An information disclosure vulnerability exists due to a failure to clear SSH-2 private key information from the memory during the saving or loading of key files to disk. A local attacker can exploit this to disclose potentially sensitive information. (CVE-2015-2157)
- An information disclose vulnerability exists in the Diffie-Hellman Key Exchange due to a failure to properly handle 0 value keys sent by the server. A man-in-the-middle attacker can exploit this to disclose potentially sensitive information. (VulnDB 136167)
SolutionUpgrade to PuTTY version 0.64 or later.
