Description

This security bulletin contains information about 1 security vulnerability.


1) Out-of-bounds write (CVE-ID: CVE-2024-9143)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error when using the low-level GF(2^m) elliptic curve APIs with untrusted explicit values for the field polynomial. A remote attacker can send specially crafted input to the server, trigger an out-of-bounds write and perform a denial of service (DoS) attack.

Note, the vulnerability can be exploited against the application in rare cases only that involve "exotic" curve encoding.
