PuTTY: Buffer overflow A buffer overflow in PuTTY might allow remote attackers to execute arbitrary code or cause a denial of service. PuTTY 2017-03-19 2017-03-19 610552 remote 0.68 0.68

PuTTY is a free implementation of Telnet and SSH for Windows and Unix platforms, along with an xterm terminal emulator.

A heap-corrupting buffer overflow bug in the ssh_agent_channel_data function of PuTTY was found.

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.

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"
