ALAS2-2019-1179


Amazon Linux 2 Security Advisory: ALAS-2019-1179
Advisory Release 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
