(CVE-2024-33600)<\/p>\n
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)<\/p>\n
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)<\/p>\n
