A journey into forgotten Null Session and MS-RPC interfaces

A journey into forgotten Null Session and MS-RPC interfaces PDF It has been almost 24 years since the null session vulnerability was discovered. Back then, it was possible to access SMB named pipes using empty credentials and collect domain information. Most often, attackers leveraged null sessio...

SUSE CVE-2023-52803

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Fix RPC client cleaned up the freed pipefs dentries RPC client pipefs dentries cleanup is in separated rpcremovepipedir workqueue,which takes care about pipefs superblock locking. In some special scenarios, when kernel...

libvirt: negative g_new0 length can lead to unbounded memory allocation

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 gnew0 function results in a crash due to the negative length being...
