Package : erlang
Version : 1:22.2.7+dfsg-1+deb10u1
CVE ID : CVE-2022-37026
Debian Bug : 1024632
A Client Authentication Bypass vulnerability has been discovered in the
concurrent, real-time, distributed functional language Erlang. Impacted are
those who are running an ssl/tls/dtls server using the ssl application
either directly or indirectly via other applications. Note that the
vulnerability only affects servers that request client certification, that
is sets the option {verify, verify_peer}.
Additionally the source package elixir-lang has been rebuilt against the new
erlang version. The rabbitmq-server package was upgraded to version 3.8.2 to
fix an incompatibility with Erlang 22.
For Debian 10 buster, this problem has been fixed in version
1:22.2.7+dfsg-1+deb10u1.
We recommend that you upgrade your erlang packages.
