GLSA-200411-22 : Davfs2, lvm-user: Insecure tempfile handling

Low Nessus Plugin ID 15723


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200411-22 (Davfs2, lvm-user: Insecure tempfile handling)

Florian Schilhabel from the Gentoo Linux Security Audit Team found that Davfs2 insecurely created .pid files in /tmp. Furthermore, Trustix Secure Linux found that the lvmcreate_initrd script, included in the lvm-user Gentoo package, also creates temporary files in world-writeable directories with predictable names.
Impact :

A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem.
When Davfs2 or lvmcreate_initrd is called, this would result in the file being overwritten with the rights of the user running the software, which could be the root user.
Workaround :

There is no known workaround at this time.


All Davfs2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-fs/davfs2-0.2.2-r1' All lvm-user users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=sys-fs/lvm-user-1.0.7-r2'
