| CVE-2023-38690 | 1 Matrix | 1 Matrix Irc Bridge | 2023-08-11 | N/A | 9.8 CRITICAL |
| matrix-appservice-irc is a Node.js IRC bridge for Matrix. Prior to version 1.0.1, it is possible to craft a command with newlines which would not be properly parsed. This would mean you could pass a string of commands as a channel name, which would then be run by the IRC bridge bot. Versions 1.0.1 and above are patched. There are no robust workarounds to the bug. One may disable dynamic channels in the config to disable the most common execution method but others may exist. | |||||
| CVE-2021-44538 | 4 Cinny Project, Debian, Matrix and 1 more | 6 Cinny, Debian Linux, Element and 3 more | 2023-08-08 | 7.5 HIGH | 9.8 CRITICAL |
| 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-2021-34813 | 1 Matrix | 1 Olm | 2021-06-23 | 7.5 HIGH | 9.8 CRITICAL |
| Matrix libolm before 3.2.3 allows a malicious Matrix homeserver to crash a client (while it is attempting to retrieve an Olm encrypted room key backup from the homeserver) because olm_pk_decrypt has a stack-based buffer overflow. Remote code execution might be possible for some nonstandard build configurations. | |||||
| CVE-2019-18835 | 1 Matrix | 1 Synapse | 2020-08-24 | 7.5 HIGH | 9.8 CRITICAL |
| Matrix Synapse before 1.5.0 mishandles signature checking on some federation APIs. Events sent over /send_join, /send_leave, and /invite may not be correctly signed, or may not come from the expected servers. | |||||
