Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Out-of-bounds write
EUVDB-ID: #VU75998
Risk: Medium
CVSSv4.0: 4.8 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2023-26551
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error within mstolfp in libntp/mstolfp.c. A remote attacker with control over a malicious NTP server can trick the victim into connecting to it, trigger an out-of-bounds write and execute arbitrary code on the target system via the client ntpq process.
