Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Stack-based buffer overflow (CVE-ID: CVE-2024-33599)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in nscd binary. A remote unauthenticated attacker can exhaust the nscd fixed size cache to trigger a stack-based buffer overflow and execute arbitrary code on the target system.



2) NULL pointer dereference (CVE-ID: CVE-2024-33600)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error when nscd cache fails to add a not-found netgroup response to the cache. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


3) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2024-33601)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to the Name Service Cache Daemon (nscd) can terminate the service during its startup. A local use can perform a denial of service (DoS) attack.


4) Buffer overflow (CVE-ID: CVE-2024-33602)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to netgroup cache assumes NSS callback is using in-buffer strings in nscd binary. A remote attacker can trigger memory corruption and perform a denial of service (DoS) attack.
