CVE-2022-24448

A flaw was found in the Linux kernel. When an application tries to open a directory using the ODIRECTORY flag in a mounted NFS filesystem, a lookup operation is performed. If the NFS server returns a file as a result of the lookup, the NFS filesystem returns an uninitialized file descriptor inste...

CVE-2022-24448

An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the ODIRECTORY flag, and tries to open a regular file, nfsatomicopen performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in...

CVE-2022-24448

CVE-2022-24448 affects the Linux kernel’s NFS path: in fs/nfs/dir.c, if an application opens a regular file with O_DIRECTORY set, nfs_atomic_open() does a regular lookup and returns uninitialized data in the file descriptor when a regular file is found instead of ENOTDIR. This issue is documented...

Vulnerabilities that aren’t. ETag headers

This time were looking at the ETag Entity Tag header. I take some of the blame for this one as I first added a dissector of the header to Nikto’s headers plugin back in 2008, then other scanners added it. What Is It? The header is a simplistic method of helping the user-agent identify whether it...
