Several vulnerabilities have been fixed in the Debian GNU C Library,
eglibc:
- CVE-2016-1234
Alexander Cherepanov discovered that the glibc’s glob implementation
suffered from a stack-based buffer overflow when it was called with the
GLOB_ALTDIRFUNC flag and encountered a long file name.
- CVE-2016-3075
The getnetbyname implementation in nss_dns was susceptible to a stack
overflow and a crash if it was invoked on a very long name.
- CVE-2016-3706
Michael Petlan reported that getaddrinfo copied large amounts of address
data to the stack, possibly leading to a stack overflow. This complements
the fix for CVE-2013-4458.
For Debian 7 Wheezy, these problems have been fixed in version
2.13-38+deb7u11.
We recommend you to upgrade your eglibc packages.
