CVE-2018-13098

Published: 3 July 2018

An issue was discovered in fs/f2fs/inode.c in the Linux kernel through 4.17.3. A denial of service (slab out-of-bounds read and BUG) can occur for a modified f2fs filesystem image in which FI_EXTRA_ATTR is set in an inode.

From the Ubuntu Security Team

Wen Xu discovered that the f2fs file system implementation in the Linux kernel did not properly validate metadata. An attacker could use this to construct a malicious f2fs image that, when mounted, could cause a denial of service (system crash).

Notes

AuthorNote
sbeattie
fix commit subject "f2fs: fix to do sanity check with
extra_attr feature"
tyhicks
The affected user base for this issue is likely small since f2fs is
not the default filesystem and it is not widely used in Ubuntu
Priority

Low

CVSS 3 base score: 5.5
