    Published: 4 Jun 2019Last Modified: 22 Apr 2026

    Summary: linux, linux-aws, linux-gcp, linux-kvm, linux-oem, linux-oracle, linux-raspi2, linux-snapdragon vulnerability

    Details: Federico Manuel Bento discovered that the Linux kernel did not properly apply Address Space Layout Randomization (ASLR) in some situations for setuid a.out binaries. A local attacker could use this to improve the chances of exploiting an existing vulnerability in a setuid a.out binary. As a hardening measure, this update disables a.out support.
