EulerOS Virtualization 2.9.1 : ntp (EulerOS-SA-2023-2964)

medium Nessus Plugin ID 188716

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the ntp package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - mstolfp in libntp/mstolfp.c in NTP 4.2.8p15 has an out-of-bounds write in the cp<cpdec while loop. An adversary may be able to attack a client ntpq process, but cannot attack ntpd. (CVE-2023-26551)

 - mstolfp in libntp/mstolfp.c in NTP 4.2.8p15 has an out-of-bounds write when adding a decimal point. An adversary may be able to attack a client ntpq process, but cannot attack ntpd. (CVE-2023-26552)

 - mstolfp in libntp/mstolfp.c in NTP 4.2.8p15 has an out-of-bounds write when copying the trailing number.
 An adversary may be able to attack a client ntpq process, but cannot attack ntpd. (CVE-2023-26553)

 - mstolfp in libntp/mstolfp.c in NTP 4.2.8p15 has an out-of-bounds write when adding a '\0' character. An adversary may be able to attack a client ntpq process, but cannot attack ntpd. (CVE-2023-26554)

 - praecis_parse in ntpd/refclock_palisade.c in NTP 4.2.8p15 has an out-of-bounds write. Any attack method would be complex, e.g., with a manipulated GPS receiver. (CVE-2023-26555)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected ntp packages.
