Security Bulletin

This security bulletin contains one low risk vulnerability.

1) Privilege escalation

EUVDB-ID: #VU13505

Risk: Low

CVSSv4.0: 7.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2018-12714

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The vulnerability exists due to the filter-parsing component, as defined in the kernel/trace/trace_events_filter.c source code file of the affected software, could be called without a filter, which would result in an N=0 case. A local attacker can make perf_event_open and mmap system calls that submit malicious input, trigger a slab out-of-bounds write condition in the predicate_parse function and cause the system to crash or execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in complete system compromise.

Mitigation

Install updates from vendor's repository.
