Background ========== Fetchmail is a utility that retrieves and forwards mail from remote systems using IMAP, POP, and other protocols. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- net-mail/fetchmail <= 6.2.4 >= 6.2.5 Description =========== Fetchmail versions 6.2.4 and earlier can be crashed by sending a specially-crafted email to a fetchmail user. This problem occurs because Fetchmail does not properly allocate memory for long lines in an incoming email. Impact ====== Fetchmail users who receive a malicious email may have their fetchmail program crash. Workaround ========== While a workaround is not currently known for this issue, all users are advised to upgrade to the latest version of the affected package. Resolution ========== Fetchmail users should upgrade to version 6.2.5 or later: # emerge sync # emerge -pv ">=net-mail/fetchmail-6.2.5" # emerge ">=net-mail/fetchmail-6.2.5" References ========== [ 1 ] http://xforce.iss.net/xforce/xfdb/13450 [ 2 ] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0792 Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
