Amazon Linux 1 Security Advisory: ALAS-2019-1179
Advisory Release Date: 2019-03-20 22:39 Pacific
Advisory Updated Date: 2019-03-25 23:05 Pacific
A kernel memory leak was found in the kernel_read_file() function in the fs/exec.c file in the Linux kernel. An attacker could use this flaw to cause a memory leak and thus a denial of service (DoS). (CVE-2019-8980)
A flaw was found in mmap in the Linux kernel allowing the process to map a null page. This allows attackers to abuse this mechanism to turn null pointer dereferences into workable exploits. (CVE-2019-9213)
Affected Packages:
kernel
Issue Correction:
