Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU68895
Risk: High
CVSSv4.0: 8.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]
CVE-ID: CVE-2022-3602
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing the email address field inside X.509 certificate. A remote attacker can supply a specially crafted certificate to the application, trigger a 4-byte buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that either a CA signs the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer.
Install update from vendor's website.

2) Buffer overflow
EUVDB-ID: #VU68896
Risk: Medium
CVSSv4.0: 6.9 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green]
CVE-ID: CVE-2022-3786
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The
vulnerability exists due to a boundary error when processing the email
address field length inside a X.509 certificate. A remote attacker can supply a
specially crafted certificate to the application, trigger a buffer overflow and crash the application.
