Synopsis ========
A buffer overflow in PuTTY might allow remote attackers to execute arbitrary code or cause a denial of service.
Background ==========

Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/putty < 0.68 >= 0.68
Description ===========
A heap-corrupting buffer overflow bug in the ssh_agent_channel_data function of PuTTY was found.
Impact ======
A remote attacker, utilizing the SSH agent forwarding of an SSH server, could execute arbitrary code with the privileges of the user running the client or cause a Denial of Service condition.
Workaround ==========
There is no known workaround at this time.

All PuTTY users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/putty-0.68"
