Amazon Linux 1 Security Advisory: ALAS-2018-1046
Advisory Release Date: 2018-07-23 20:51 Pacific
Advisory Updated Date: 2018-07-24 21:06 Pacific
Severity:
Medium
Issue Overview:
The fs/ext4/inline.c:ext4_read_inline_data() function in the Linux kernel performs a memcpy with an untrusted length value in certain circumstances involving a crafted filesystem that stores the system.data extended attribute value in a dedicated inode. The unbound copy can cause memory corruption or possible privilege escalation. (CVE-2018-11412)
Affected Packages:
kernel
