glibc is vulnerable to denial of service. It was found that the glibc addmntent() function, used by various mount helper utilities, did not handle certain errors correctly when updating the mtab (mounted file systems table) file. If such utilities had the setuid bit set, a local attacker could use this flaw to corrupt the mtab file.
