CVE-2017-17843 describes a medium-severity vulnerability in Enigmail versions prior to 1.9.9, affecting Debian Linux and Enigmail installations. The flaw allows remote attackers to force the use of an unintended public key for encryption due to incorrect regular expressions used in extracting email addresses from comma-separated lists, potentially leading to a homograph attack. While the attack complexity is high, it requires no user interaction and could result in a high impact on integrity, though confidentiality and availability are not affected. Currently, there is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
