Several vulnerabilities have been fixed in the Debian GNU C Library,
eglibc:
- 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.
