Description
This security bulletin contains information about 1 security vulnerability.
1) Comparison using wrong factors (CVE-ID: CVE-2024-9681)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to an error in HSTS cache implementation. When curl is asked to use HSTS, the expiry time for a subdomain can overwrite a parent domain's cache entry, making it end sooner or later
than otherwise intended. This can lead to situations when the website becomes unavailable or force the client to switch to HTTP from HTTP connection earlier than intended.
Remediation
Install update from vendor's website.
