CVE-2018-10877

Priority
Description
Linux kernel ext4 filesystem is vulnerable to an out-of-bound access in the
ext4_ext_drop_refs() function when operating on a crafted ext4 filesystem
image.
Ubuntu-Description
Wen Xu discovered that a buffer overflow existed in the ext4 filesystem
implementation in the Linux kernel. An attacker could use this to construct
a malicious ext4 image that, when mounted, could cause a denial of service
(system crash) or possibly execute arbitrary code.
