Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Memory leak
EUVDB-ID: #VU46074
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2020-5926
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak in Virtual server using the SIP ALG profile. A remote attacker can send specially crafted SIP messages that contain a multi-part MIME payload and perform denial of service attack.
MitigationInstall updates from vendor's website.
