Description
The vulnerability allows a local attacker to cause DoS condition on the target system.
The vulnerability exists due to NULL pointer dereference when the hfsplus_lookup() function, as defined in the fs/hfsplus/dir.c source code file of the affected software, opens a file in a read-only Hierarchical File System Plus (HFS+) filesystem without a metadata directory and with malformed catalog data. A local attacker can mount a malicious HFS+ filesystem image, open a file in the image and cause kernel panic.
Remediation
