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.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6804-1 advisory.

    It was discovered that GNU C Library nscd daemon contained a stack-based buffer overflow. A local attacker     could use this to cause a denial of service (system crash). (CVE-2024-33599)

    It was discovered that GNU C Library nscd daemon did not properly check the cache content, leading to a     null pointer dereference vulnerability. A local attacker could use this to cause a denial of service     (system crash). (CVE-2024-33600)

    It was discovered that GNU C Library nscd daemon did not properly validate memory allocation in certain     situations, leading to a null pointer dereference vulnerability. A local attacker could use this to cause     a denial of service (system crash). (CVE-2024-33601)

    It was discovered that GNU C Library nscd daemon did not properly handle memory allocation, which could     lead to memory corruption. A local attacker could use this to cause a denial of service (system crash).
