Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Use-after-free
EUVDB-ID: #VU27376
Risk: Medium
CVSSv4.0: 2.1 [CVSS:4.0/AV:A/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2020-10700
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a use-after-free error when Paged results control is combined with ASQ control while performing search operations. A remote authenticated user can send a specially crafted LDAP search query, trigger a use-after-free error and perform a denial of service attack.
Install updates from vendor's repository.
