An update that fixes three vulnerabilities is now available.
Description:
This update for the Linux Kernel 4.12.14-95_74 fixes several issues.
The following security issues were fixed:
- CVE-2018-25020: Fixed an issue in the BPF subsystem in the Linux kernel mishandled situations with a long jump over an instruction sequence where inner instructions require substantial expansions into multiple BPF instructions, leading to an overflow. (bsc#1193575) - CVE-2020-3702: Fixed a bug which could be triggered with specifically timed and handcrafted traffic and cause internal errors in a WLAN device that lead to improper layer 2 Wi-Fi encryption with a consequent possibility of information disclosure. (bsc#1191193) - CVE-2021-42739: The firewire subsystem had a buffer overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandled bounds checking (bsc#1184673).
