Beschreibung:	Summary: The remote host is missing an update for the 'olm' package(s) announced via the MGASA-2021-0571 advisory. Vulnerability Insight: Updated olm packages fix security vulnerability: 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 (CVE-2021-44538). Affected Software/OS: 'olm' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 7.5 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
