RHSA-2010:0787-01: [RHSA-2010:0787-01] Important: glibc security update
Product: Red Hat Enterprise Linux

The glibc packages contain the standard C libraries used by multiple

programs on the system. These packages contain the standard C and the

standard math libraries. Without these two libraries, a Linux system cannot

function properly.

It was discovered that the glibc dynamic linker/loader did not handle the

$ORIGIN dynamic string token set in the LD_AUDIT environment variable

securely. A local attacker with write access to a file system containing

setuid or setgid binaries could use this flaw to escalate their privileges.
