SUSE update for mozilla-nss

1) Heap-based buffer overflow

EUVDB-ID: #VU58477

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2021-43527

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when handling DER-encoded DSA or RSA-PSS signatures. A remote attacker can send specially crafted signatures encoded within CMS, S/MIME, PKCS #7, or PKCS #12 to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected package mozilla-nss to the latest version.
