      <Note Type="Summary" Ordinal="001">An update for glibc is now available for HCE 2.0

HCE Security has rated this update as having a security impact of Important.A Common Vunlnerability Scoring System(CVSS)base score, which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
      <Note Type="General" Ordinal="002">Security Fix(es):

nscd: netgroup cache may terminate daemon on memory allocation failure

The Name Service Cache Daemon_x27;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.

 (CVE-2024-33601)

nscd: Null pointer crashes after notfound response

If the Name Service Cache Daemon_x27;s (nscd) cache fails to add a not-found
netgroup response to the cache, the client request can result in a null
pointer dereference.  This flaw was introduced in glibc 2.15 when the
cache was added to nscd.

This vulnerability is only present in the nscd binary.

 (CVE-2024-33600)

nscd: Stack-based buffer overflow in netgroup cache

If the Name Service Cache Daemon_x27;s (nscd) fixed size cache is exhausted
by client requests then a subsequent client request for netgroup data
may result in a stack-based buffer overflow.  This flaw was introduced
in glibc 2.15 when the cache was added to nscd.

This vulnerability is only present in the nscd binary.
 (CVE-2024-33599)

nscd: netgroup cache assumes NSS callback uses in-buffer strings

The Name Service Cache Daemon_x27;s (nscd) netgroup cache can corrupt memory
when the NSS callback does not store all strings in the provided buffer.
The flaw was introduced in glibc 2.15 when the cache was added to nscd.

This vulnerability is only present in the nscd binary.

 (CVE-2024-33602)
