| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L |
Name of the Vulnerable Software and Affected Versions
glibc versions 2.15 and later
Description
The issue is related to the Name Service Cache Daemon's (nscd) netgroup cache, which uses
xmalloc or xrealloc functions. 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.Recommendations
For glibc versions 2.15 and later, consider disabling the netgroup cache in nscd as a temporary workaround to minimize the risk of exploitation. Restrict access to the nscd binary to prevent potential attacks. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
