Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:
- In the Linux kernel, the following vulnerability has been resolved: xfs: add bounds checking to
xlog_recover_process_data There is a lack of verification of the space occupied by fixed members of
xlog_op_header in the xlog_recover_process_data. We can create a crafted image to trigger an out of bounds
read by following these steps: 1) Mount an image of xfs, and do some file operations to leave records 2)
Before umounting, copy the image for subsequent steps to simulate abnormal exit. Because umount will
ensure that tail_blk and head_blk are the same, which will result in the inability to enter
xlog_recover_process_data 3) Write a tool to parse and modify the copied image in step 2 4) Make the end
of the xlog_op_header entries only 1 byte away from xlog_rec_header->h_size 5)
xlog_rec_header->h_num_logops++ 6) Modify xlog_rec_header->h_crc Fix: Add a check to make sure there is
sufficient space to access fixed members of xlog_op_header. (CVE-2024-41014)
