Vulnerabilities description

  • CVE-2024-33599

    A stack-based buffer overflow flaw was found in the glibc netgroup cache. In certain conditions, its possible to trigger a stack-based buffer overflow condition that can lead to a denial of service and potentially other malicious actions that impact confidentiality and integrity.

  • CVE-2024-33600

    A flaw was found in the glibc netgroup cache. After a failed cache insertion, addgetnetgrentX tries to send the non-existing response after the not-found header. This can lead to a null pointer dereference that causes a crash or exit.

  • CVE-2024-33601

    A flaw was found in the glibc netgroup cache. The netgroup cache uses xmalloc/xrealloc and may terminate the process due to a memory allocation failure.

  • CVE-2024-33602

    A flaw was found in the glibc netgroup cache. The buffer-resizing code in addgetnetgrentX assumes that all string pointers point into the supplied buffer. This can potentially lead to memory corruption and cause a crash.
