CVE-2015-5309

Publication date 7 December 2015

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

Integer overflow in the terminal emulator in PuTTY before 0.66 allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via an ECH (erase characters) escape sequence with a large parameter value, which triggers a buffer underflow.
