[ASA-201905-4] linux-zen: arbitrary code execution
Arch Linux Security Advisory ASA-201905-4 ========================================= Severity: High Date : 2019-05-06 CVE-ID : CVE-2019-11683 Package : linux-zen Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-957 Summary ======= The package <a href="/package/linux-zen">linux-zen</a> before version 5.0.12.zen2-1 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 5.0.12.zen2-1. # pacman -Syu "linux-zen>=5.0.12.zen2-1" The problem has been fixed upstream in version 5.0.12.zen2. Workaround ========== None. Description =========== udp_gro_receive_segment in net/ipv4/udp_offload.c in the Linux kernel 5.x through 5.0.11 allows remote attackers to cause a denial of service (slab-out-of-bounds memory corruption) or possibly have unspecified other impact via UDP packets with a 0 payload, because of mishandling of padded packets, aka the "GRO packet of death" issue. Impact ====== A remote attacker is able to cause a denial of service possibly leading to remote code execution by sending UDP packets with a special payload.
