Synopsis ========
Qpopper contains two vulnerabilities allowing an attacker to overwrite arbitrary files and create files with insecure permissions.
Background ==========
Qpopper is a widely used server for the POP3 protocol.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-mail/qpopper < 4.0.5-r3 >= 4.0.5-r3
Description ===========
Jens Steube discovered that Qpopper doesn't drop privileges to process local files from normal users (CAN-2005-1151). The upstream developers discovered that Qpopper can be forced to create group or world writeable files (CAN-2005-1152).
Impact ======
A malicious local attacker could exploit Qpopper to overwrite arbitrary files as root or create new files which are group or world writeable.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Qpopper users should upgrade to the latest available version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-mail/qpopper-4.0.5-r3"
