CVE-2017-18350

bitcoind and Bitcoin-Qt prior to 0.15.1 have a stack-based buffer overflow if an attacker-controlled SOCKS proxy server is used.

MEDIUM 5.9EPSS 1.60%

Does this matter?

Lower severity and a low EPSS score (1.60%). Track it; it rarely justifies an emergency change on its own.

Description

bitcoind and Bitcoin-Qt prior to 0.15.1 have a stack-based buffer overflow if an attacker-controlled SOCKS proxy server is used. This results from an integer signedness error when the proxy server responds with an acknowledgement of an unexpected target domain name.
