Summary

Details

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.

Summary

glibc vulnerabilities

Details

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). (CVE-2024-33602)
