Details

USN-1009-1 fixed vulnerabilities in the GNU C library. Colin Watson
discovered that the fixes were incomplete and introduced flaws with
setuid programs loading libraries that used dynamic string tokens in their
RPATH. If the “man” program was installed setuid, a local attacker could
exploit this to gain “man” user privileges, potentially leading to further
privilege escalations. Default Ubuntu installations were not affected.

Original advisory details:

Tavis Ormandy discovered multiple flaws in the GNU C Library’s handling
of the LD_AUDIT environment variable when running a privileged binary. A
local attacker could exploit this to gain root privileges. (CVE-2010-3847,
CVE-2010-3856)
