Synopsis ========
cmd5checkpw contains a flaw allowing local users to access other users cmd5checkpw passwords.
Background ==========
cmd5checkpw is a checkpassword compatible authentication program that uses CRAM-MD5 authentication mode.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-mail/cmd5checkpw <= 0.22-r1 >= 0.22-r2
Description ===========
Florian Westphal discovered that cmd5checkpw is installed setuid cmd5checkpw but does not drop privileges before calling execvp(), so the invoked program retains the cmd5checkpw euid.
Impact ======
Local users that know at least one valid /etc/poppasswd user/password combination can read the /etc/poppasswd file.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All cmd5checkpw users should upgrade to the latest available version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-mail/cmd5checkpw-0.22-r2"
Availability ============
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:
