The glibc packages contain the standard C libraries used by multipleprograms on the system. These packages contain the standard C and thestandard math libraries. Without these two libraries, a Linux system cannotfunction properly.It was discovered that the glibc dynamic linker/loader did not handle the$ORIGIN dynamic string token set in the LDAUDIT environment variablesecurely. A local attacker with write access to a file system containingsetuid or setgid binaries could use this flaw to escalate their privileges.(CVE-2010-3847)Red Hat would like to thank Tavis Ormandy for reporting this issue.All users should upgrade to these updated packages, which contain abackported patch to correct this issue.
