Amazon Linux 2 : qemu, --advisory ALAS2-2025-3044 (ALAS-2025-3044)
The version of qemu installed on the remote host is prior to 3.1.0-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-3044 advisory. A flaw was found in QEMU. If the QIOChannelWebsock object is freed while it is waiting to complete a handshake, a GSource is leaked...
Important: qemu
Issue Overview: A flaw was found in QEMU. If the QIOChannelWebsock object is freed while it is waiting to complete a handshake, a GSource is leaked. This can lead to the callback firing later on and triggering a use-after-free in the use of the channel. This can be abused by a malicious client wi...
OpenVPN -- HMAC verification on source IP address ineffective
Arne Schwabe reports: Fix memcmp check for the hmac verification in the 3way handshake being inverted This is a stupid mistake but causes all hmac cookies to be accepted, thus breaking source IP address validation. As a consequence, TLS sessions can be openend and state can be consumed in the...
