CVE-2004-1008
Integer signedness error in the ssh2_rdpkt function in PuTTY before 0.56 allows remote attackers to execute arbitrary code via a SSH2_MSG_DEBUG packet with a modified stringlen parameter, which leads to a buffer overflow.

Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (7.36%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
