Summary:	NTP is prone to multiple vulnerabilities.
Description:	Summary: NTP is prone to multiple vulnerabilities. Vulnerability Insight: The following flaws exist: - CVE-2023-26551: mstolfp in libntp/mstolfp.c has an out-of-bounds write in the cp loop. An adversary may be able to attack a client ntpq process, but cannot attack ntpd. - CVE-2023-26552: mstolfp in libntp/mstolfp.c 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-2023-26553: mstolfp in libntp/mstolfp.c 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-2023-26554: mstolfp in libntp/mstolfp.c 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-2023-26555: praecis_parse in ntpd/refclock_palisade.c has an out-of-bounds write. Any attack method would be complex, e.g., with a manipulated GPS receiver. Affected Software/OS: NTPd version 4.2.8p15 and prior. Solution: Update to version 4.2.8p16 or later.
