CVE-2026-70368

A stack-based out-of-bounds read vulnerability exists in the "svlog" function of stunnel, when handling oversized log messages via "vsnprintf". A remote attacker with network access to a stunnel service can send protocol inputs that trigger a log message longer than 1024 bytes, leading to an...

AZL-94577 CVE-2026-70367 affecting package stunnel 5.74-1

A Server-Side Request Forgery SSRF bypass vulnerability exists in “stunnel” 5.79 and lower when configured in SOCKS proxy mode. This flaw allows a client to bypass intended localhost restrictions by using IPv4-mapped IPv6 addresses e.g., “::ffff:127.0.0.1” or unspecified addresses "0.0.0.0", "::"...
