1) Out-of-bounds read

EUVDB-ID: #VU93424

Risk: Low

CVSSv4.0: [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

Description

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

The vulnerability exists due to a boundary condition within the SSL_select_next_proto() function when using NPN. A remote attacker can send specially crafted data to the application, trigger an out-of-bounds read and perform a denial of service (DoS) attack.

Mitigation

Update the affected package openssl-1_1 to the latest version.
