Amazon Linux 2 Security Advisory: ALAS-2019-1179
Advisory Release Date: 2019-03-21 19:26 Pacific
Advisory Updated Date: 2019-03-28 17:45 Pacific
Severity:
Important
Issue Overview:
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
