Alpine: multiple synapse packages: security update to 1.29.0-r0 (deprecated)
medium Tenable Cloud Security Plugin ID 400252
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a
client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was
present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL
pointer dereference will result, leading to a crash and a denial of service attack. A server is only
vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS
clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of
these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in
OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j). (CVE-2021-3449)
