Security Bulletin
This security bulletin contains one high risk vulnerability.
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
DescriptionThe 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.
MitigationInstall update from vendor's website.
