Alpine: riot-web: security update to 1.9.6-r0 (deprecated)

critical Tenable Cloud Security Plugin ID 400035

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- The olm_session_describe function in Matrix libolm before 3.2.7 is vulnerable to a buffer overflow. The
Olm session object represents a cryptographic channel between two parties. Therefore, its state is
partially controllable by the remote party of the channel. Attackers can construct a crafted sequence of
messages to manipulate the state of the receiver's session in such a way that, for some buffer sizes, a
buffer overflow happens on a call to olm_session_describe. Furthermore, safe buffer sizes were
undocumented. The overflow content is partially controllable by the attacker and limited to ASCII spaces
and digits. The known affected products are Element Web And SchildiChat Web. (CVE-2021-44538)
