Security Bulletin
This security bulletin contains one medium risk vulnerability.
1) Memory leak
EUVDB-ID: #VU73248
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-2021-3905
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 lib/ipf.c during userspace IP fragmentation processing. A remote attacker can send specially crafted packet fragments to the system to trigger memory leak and perform denial of service attack.
MitigationInstall updates from vendor's repository.
