CVE-2014-9761

The math's nan* function wrongly handled payload strings, yielding to an unbounded stack allocation based on the length of the arguments. To solve this issue, payload parsing has been refactored out of strtod into a separate functions that nan* can call directly.

CVE-2015-8776

The strftime() function made it possible to access invalid memory, allowing to segfault the calling application.

CVE-2015-8778

hcreate() was susceptible to an integer overflow, that may results in out-of-bounds heap accesses.

CVE-2015-8779

The catopen() function suffered from multiple unbounded stack allocations.

For Debian 6 Squeeze, these issues have been fixed in eglibc version eglibc_2.11.3-4+deb6u9. We recommend you to upgrade your eglibc packages.");
