Heap overflow

Heap-based buffer overflow in the nsshostnamedigitsdots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the 1 gethostbyname or 2 gethostbyname2 function, aka "GHOST."...

CVE-2015-0235

CVE-2015-0235 (GHOST) is a heap-based buffer overflow in glibc’s __nss_hostname_digits_dots() used by gethostbyname/gethostbyname2. Affected glibc versions include 2.2 up to 2.17; patched in glibc-2.18 and later. Exploitation could allow remote or context-dependent arbitrary code execution depend...

glibc 2.2 local vulnerability on setuid binaries

glibc-2.2 contains a local vulnerability that affects all setuid root binaries. Any user on affected systems will be able to read any file on the system through a simple process: The user sets the RESOLVHOSTCONF environment variable to the name of the file that they wish to read, then runs any...
