Background ========= fetchmail is a utility that retrieves and forwards mail from remote systems using IMAP, POP, and other protocols. It ships with fetchmailconf, a graphical utility used to create configuration files. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-mail/fetchmail < 6.2.5.2-r1 > = 6.2.5.2-r1 Description ========== Thomas Wolff discovered that fetchmailconf opens the configuration file with default permissions, writes the configuration to it, and only then restricts read permissions to the owner. Impact ===== A local attacker could exploit the race condition to retrieve sensitive information like IMAP/POP passwords. Workaround ========= Run "umask 077" to temporarily strengthen default permissions, then run "fetchmailconf" from the same shell. Resolution ========= All fetchmail users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-mail/fetchmail-6.2.5.2-r1" References ========= [ 1 ] Fetchmail Security Advisory https://www.berlios.de/software/fetchmail/ [ 2 ] CVE-2005-3088 https://www.cve.org/CVERecord?id=CVE-2005-3088 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200511-06 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.
