SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200903-39 (pam_krb5: Privilege escalation)
The following vulnerabilities were discovered:
pam_krb5 does not properly initialize the Kerberos libraries for setuid use (CVE-2009-0360).
Derek Chan reported that calls to pam_setcred() are not properly handled when running setuid (CVE-2009-0361).
A local attacker could set an environment variable to point to a specially crafted Kerberos configuration file and launch a PAM-based setuid application to elevate privileges, or change ownership and overwrite arbitrary files.
There is no known workaround at this time.
SolutionAll pam_krb5 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=sys-auth/pam_krb5-3.12'
