CVE-2016-4913 (retired)

Priority
Description
The get_rock_ridge_filename function in fs/isofs/rock.c in the Linux kernel
before 4.5.5 mishandles NM (aka alternate name) entries containing \0
characters, which allows local users to obtain sensitive information from
kernel memory or possibly have unspecified other impact via a crafted isofs
filesystem.
Ubuntu-Description
It was discovered that an information leak exists in the Rock Ridge
implementation in the Linux kernel. A local attacker who is able to mount a
malicious iso9660 file system image could exploit this flaw to obtain
potentially sensitive information from kernel memory.
