format string, a remote attacker could crash applications, leading to
a denial of service. (Ubuntu 10.04 was not affected.) (CVE-2008-1391)

Jeff Layton and Dan Rosenberg discovered that the GNU C library did not
correctly handle newlines in the mntent family of functions. If a local
attacker were able to inject newlines into a mount entry through other
vulnerable mount helpers, they could disrupt the system or possibly gain
root privileges. (CVE-2010-0296)

Dan Rosenberg discovered that the GNU C library did not correctly validate
certain ELF program headers. If a user or automated system were tricked
into verifying a specially crafted ELF program, a remote attacker could
execute arbitrary code with user privileges. (CVE-2010-0830)");
