Detailsinfo

A vulnerability, which was classified as problematic, was found in Vert.x up to 4.5.2. Affected is an unknown function of the component SNI Handler. The manipulation with an unknown input leads to a memory leak vulnerability. CWE is classifying the issue as CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. This is going to have an impact on availability. CVE summarizes:

A vulnerability in the Eclipse Vert.x toolkit causes a memory leak in TCP servers configured with TLS and SNI support. When processing an unknown SNI server name assigned the default certificate instead of a mapped certificate, the SSL context is erroneously cached in the server name map, leading to memory exhaustion. This flaw allows attackers to send TLS client hello messages with fake server names, triggering a JVM out-of-memory error.

The weakness was disclosed 02/07/2024. The advisory is shared for download at bugzilla.redhat.com. This vulnerability is traded as CVE-2024-1300. There are neither technical details nor an exploit publicly available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2024-1174). Once again VulDB remains the best source for vulnerability data.
