Alpine: multiple openvpn packages: security update to 2.7.5-r0

high Tenable Cloud Security Plugin ID 444654

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - An incomplete guard in OpenVPN 2.6.0 through 2.6.20 and 2.7_alpha1 through 2.7.4 allows remote
 authenticated peers to trigger a use-after-free during TLS session promotion, potentially leading to a
 denial of service or memory leakage (CVE-2026-13117)

 - OpenVPN version 2.1.0 through 2.6.20 and 2.7_alpha1 through 2.7.4 allows attackers via an off-by-one
 buffer write in the NTLM proxy authentication to potentially cause a crash via a crafted NTLM response
 from a malicious proxy server (CVE-2026-11771)

 - A memory leak in the tls-crypt-v2 client key extraction in OpenVPN 2.5.0 through 2.6.20 and 2.7_alpha1
 through 2.7.4 allows remote attackers to cause a denial of service (memory exhaustion) via a flood of
 crafted packets (CVE-2026-12932)

 - A use-after-free in OpenVPN 2.6.0 through 2.6.20 and 2.7_alpha1 through 2.7.4 allows remote authenticated
 peers to potentially cause a denial of service or leak memory via crafted packets during TLS session
 promotion or expiry (CVE-2026-12996)

Solution

Update the openvpn library and its related packages to version 2.7.5-r0 or later.
