Astra Linux – Vulnerability in glibc

NSCD: The NetGroup Cache may terminate the daemon due to a memory allocation failure. The NetGroup Cache Daemon’s NSCD netgroup cache uses xmalloc or xrealloc, and these functions may terminate the process due to a memory allocation failure, resulting in a denial of service for clients. This flaw...

Astra Linux – Vulnerability in glibc

The name server caching daemon nscd in the GNU C Library also known as glibc or libc6 versions 2.29 through 2.33 may crash when processing a request for netgroup lookup. This can potentially lead to degraded service or a Denial of Service on the local system. This issue is related to the...

Astra Linux – Vulnerability in glibc

nscd: Null pointer crash after a “notfound” response If the Name Service Cache Daemon’s nscd cache fails to add a “notfound” netgroup response to its cache, the client request may lead to a null pointer dereferencing. This flaw was introduced in glibc 2.15 when the cache was moved to nscd. This...
