vulnerabilities found in GNU glibc.
Vulnerability Details
CVEID:
CVE-2016-3075
DESCRIPTION:
GNU C Library (glibc) is vulnerable to a stack-based buffer overflow, caused
by improper bounds checking by the nss_dns implementation of the getnetbyname
function. By sending an overly long string, a remote attacker could overflow
a buffer and execute arbitrary code on the system or cause the application to
crash.
CVSS Base Score: 7.3

DESCRIPTION:
glibc is vulnerable to a denial of service, caused by a stack-based buffer
overflow within the glob implementation when GLOB_ALTDIRFUNC is used. A
