"The remote NewStart CGSL host, running version MAIN 7.02, has glibc packages installed that are affected by multiple
vulnerabilities:

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

  - nscd: Stack-based buffer overflow in netgroup cache If the Name Service Cache Daemon'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: Null pointer crashes after notfound response If the Name Service Cache Daemon'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: 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.
    (CVE-2024-33601)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
