Detailsinfo

A vulnerability classified as problematic has been found in ntp up to 4.2.8p14/4.3.100 (Network Management Software). This affects an unknown code block of the component ntpd. The manipulation as part of a Packet leads to a memory allocation vulnerability. CWE is classifying the issue as CWE-789. The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated. This is going to have an impact on availability. The summary by CVE is:

ntpd in ntp 4.2.8 before 4.2.8p15 and 4.3.x before 4.3.101 allows remote attackers to cause a denial of service (memory consumption) by sending packets, because memory is not freed in situations where a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file.

The weakness was shared 06/24/2020. This vulnerability is uniquely identified as CVE-2020-15025 since 06/24/2020. The exploitability is told to be difficult. It is possible to initiate the attack remotely. Additional levels of successful authentication are needed for exploitation.
