Tracker summary

CVE-2013-4852 low priority: Debian including 2 source packages (filezilla, putty), 10 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 10.

Description:

Integer overflow in PuTTY 0.62 and earlier, WinSCP before 5.1.6, and other products that use PuTTY allows remote SSH servers to cause a denial of service (crash) and possibly execute arbitrary code in certain applications that use PuTTY via a negative size value in an RSA key signature during the SSH handshake, which triggers a heap-based buffer overflow.
