Amazon Linux 2 Security Advisory: ALAS-2024-2513
Advisory Release Date: 2024-04-11 01:07 Pacific
Advisory Updated Date: 2024-04-15 12:00 Pacific
Severity:
Medium
Issue Overview:
An off-by-one error flaw was found in the udevListInterfacesByStatus() function in libvirt when the number of interfaces exceeds the size of the `names` array. This issue can be reproduced by sending specially crafted data to the libvirt daemon, allowing an unprivileged client to perform a denial of service attack by causing the libvirt daemon to crash. (CVE-2024-1441)
A flaw was found in the RPC library APIs of libvirt. The RPC server deserialization code allocates memory for arrays before the non-negative length check is performed by the C API entry points. Passing a negative length to the g_new0 function results in a crash due to the negative length being treated as a huge positive number. This flaw allows a local, unprivileged user to perform a denial of service attack by causing the libvirt daemon to crash. (CVE-2024-2494)
NULL pointer dereference in udevConnectListAllInterfaces() (CVE-2024-2496)
