glibc: glibc: Incorrect DNS response parsing via crafted DNS server response

A flaw was found in glibc the GNU C Library. When an application uses the gethostbyaddr or gethostbyaddrr functions with a nsswitch.conf configuration that specifies glibc's DNS backend, a remote attacker can send a specially crafted DNS Domain Name System response. This crafted response can caus...

glibc: glibc: Information disclosure via zero-valued network query

A flaw was found in glibc, the GNU C Library. When an application calls the getnetbyaddr or getnetbyaddrr functions to resolve a network address, and the system's nsswitch.conf file is configured to use a DNS Domain Name System backend for network lookups, a query for a zero-valued network can le...

glibc: glibc: Invalid DNS hostname returned via gethostbyaddr functions

A flaw was found in the GNU C library glibc. When applications use the gethostbyaddr or gethostbyaddrr functions with a nsswitch.conf configuration that specifies glibc's DNS backend, the library may return an invalid DNS hostname. This violates the DNS specification and could lead to application...
