OpenSUSE Linux update for redis

1) Input validation error

EUVDB-ID: #VU30255

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2020-14147

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows context-dependent attackers with permission to run Lua code in a Redis session to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (memory corruption and application crash) or possibly bypass intended sandbox restrictions via a large number, which triggers a stack-based buffer overflow.

Mitigation

Update the affected packages.
