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...

Astra Linux – Vulnerability in glibc

A flaw has been identified in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the nssgethostbyname2r and nssgetcanonnamer hooks without...

Astra Linux – Vulnerability in glibc

The Name Service Cache Daemon’s nscd netgroup cache can corrupt memory when the NSS callback does not store all strings in the provided buffer. This flaw was introduced in glibc 2.15, when the cache was added to nscd. This vulnerability only exists in the nscd binary...

Astra Linux – Vulnerability in glibc

Calling getnetbyaddr or getnetbyaddrr with a configured nsswitch.conf that specifies the library’s DNS backend can lead to a situation where a zero-valued network is queried during operations in the GNU C Library versions 2.0 to 2.42. This could result in the leakage of stack contents to the...
