Details

nscd: netgroup cache may terminate daemon on memory allocation failure

The Name Service 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 to the clients. The flaw was introduced in glibc 2.15 when the cache was added to nscd.

This vulnerability is only present in the nscd binary.

Severity

7.5 (High)
