Debian DLA-970-1 : sudo security update
Medium Nessus Plugin ID 100519
SynopsisThe remote Debian host is missing a security update.
DescriptionThe Qualys Security team discovered that sudo, a program designed to provide limited super user privileges to specific users, does not properly parse '/proc/[pid]/stat' to read the device number of the tty from field 7 (tty_nr). A sudoers user can take advantage of this flaw on an SELinux-enabled system to obtain full root privileges.
For Debian 7 'Wheezy', this problem has been fixed in version 1.8.5p2-1+nmu3+deb7u3.
For Debian 8 'Jessie', this problem has been fixed in version 1.8.10p3-1+deb8u4.
We recommend that you upgrade your sudo packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpgrade the affected sudo, and sudo-ldap packages.
