Denial of Service (DoS) Affecting openssl-src package, versions <300.2.0+3.2.0
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

CVE-2023-5678 (opens in a new tab)How to fix?
Upgrade openssl-src to version 300.2.0+3.2.0 or higher.
Overview
openssl-src is a crate that contains the logic to build OpenSSL and is intended to be consumed by the openssl-sys crate.
Affected versions of this package are vulnerable to Denial of Service (DoS) when the DH_generate_key(), DH_check_pub_key(), DH_check_pub_key_ex(), EVP_PKEY_public_check(), and EVP_PKEY_generate() functions are used. An attacker can cause long delays and potentially a Denial of Service by supplying excessively long X9.42 DH keys or parameters obtained from an untrusted source.
Note:
This is only exploitable if the application uses these functions to generate or check an X9.42 DH key or parameters. Also, the OpenSSL pkey command line application, when using the -pubcheck option, as well as the OpenSSL genpkey command line application, are vulnerable to this issue.
