OpenSSH is prone to a local information-disclosure vulnerability.

Local attackers can exploit this issue to obtain sensitive information. Information obtained may lead to further attacks.

Updates are available.

ssh-keysign.c in ssh-keysign in OpenSSH before 5.8p2 on certain platforms executes ssh-rand-helper with unintended open file descriptors, which allows local users to obtain sensitive key information via the ptrace system call.

Versions prior to OpenSSH 5.8p2 are vulnerable.

Check the version.
