Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU61205
Risk: Low
CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-25020
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the BPF subsystem in the Linux kernel in ernel/bpf/core.c and net/core/filter.c. The kernel mishandles situations with a long jump over an instruction sequence
where inner instructions require substantial expansions into multiple
BPF instructions. A local user can run a specially crafted program to trigger memory corruption and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel (Live Patch 41 for SLE 12 SP3) to the latest version.

2) Resource exhaustion
EUVDB-ID: #VU19181
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-0136
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to the software does not properly control the allocation and maintenance of a limited resource. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
The vulnerability affects Intel Dual Band Wireless-AC 8260 Windows10 Driver
MitigationUpdate the affected package the Linux Kernel (Live Patch 41 for SLE 12 SP3) to the latest version.
