CVE-2014-8121

CVE-2014-8121 affects the GNU C Library (glibc/eglibc) NSS backend: DB_LOOKUP in nss_files/files-XXX.c can loop indefinitely when a file is being iterated, by not properly checking if the database file is open. This can lead to a denial of service. The affected line of code is in the NSS file bac...

A vulnerability has been fixed in eglibc, Debian's version of the GNU C library : CVE-2015-0235 Qualys discovered that the gethostbyname and gethostbyname2 functions were subject to a buffer overflow if provided with a crafted IP address argument. This could be used by an attacker to execute...

GNU glibc denial of service vulnerability (CNVD-2015-01962)

glibc is the libc library, or c runtime library, released by GNU. glibc is the lowest level api in the linux system, and almost any other runtime library will depend on glibc. Name Service Switch NSS's file backend fails to isolate the entire database iteration from key-based query API calls, and...

glibc: Unexpected closing of nss_files databases after lookups causes denial of service

It was found that the files back end of Name Service Switch NSS did not isolate iteration over an entire database from key-based look-up API calls. An application performing look-ups on a database while iterating over it could enter an infinite loop, leading to a denial of service...
