Description Vasyl Kaigorodov 2014-09-15 13:43:54 UTC

Linux kernel built with the UDF file system support(CONFIG_UDF_FS) is vulnerable
to a crash due to stack overflow through infinite recursion. It occurs while traversing a long ICB hierarchy.

a user/program able to mount such a file system could use this flaw to crash the system kernel resulting in DoS.

Comment 11 Martin Prpič 2014-09-30 10:45:33 UTC

IssueDescription:

A stack overflow flaw caused by infinite recursion was found in the way the Linux kernel's Universal Disk Format (UDF) file system implementation processed indirect Information Control Blocks (ICBs). An attacker with physical access to the system could use a specially crafted UDF image to crash the system.
