[ASA-201811-1] linux: denial of service
Arch Linux Security Advisory ASA-201811-1 ========================================= Severity: Low Date : 2018-11-01 CVE-ID : CVE-2018-18445 Package : linux Type : denial of service Remote : No Link : Summary ======= The package linux before version 4.18.13.arch1-1 is vulnerable to denial of service. Resolution ========== Upgrade to 4.18.13.arch1-1. # pacman -Syu "linux>=4.18.13.arch1-1" The problem has been fixed upstream in version 4.18.13.arch1. Workaround ========== None. Description =========== In the Linux kernel 4.14.x before 4.14.75 and 4.18.x before 4.18.13, faulty computation of numeric bounds in the BPF verifier permits out- of-bounds memory accesses because adjust_scalar_min_max_vals in kernel/bpf/verifier.c mishandles 32-bit right shifts. Impact ====== A local attacker is able to crash the kernel and leak information using a specially crafted BPF program. References ==========
