Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Use-after-free
EUVDB-ID: #VU55006
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-2021-36980
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in decode_NXAST_RAW_ENCAP (called from ofpact_decode and ofpacts_decode) during the decoding of a RAW_ENCAP action. A remote attacker can send a specially crafted request to the system, trigger a use-after-free error and execute arbitrary code.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
MitigationUpdate the affected package openvswitch to the latest version.

2) Out-of-bounds read
EUVDB-ID: #VU68717
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-2022-32166
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the minimasks() function in flow.c. A remote attacker can pass specially crafted data to the application, trigger an out-of-bounds read error and crash the service.
Update the affected package openvswitch to the latest version.
