2024-08-22 CVE-2024-45191 An issue was discovered in Matrix libolm through 3.2.16. The AES implementation is vulnerable to cache-timing attacks due to use of S-boxes. This is related to software that uses a lookup table for the SubWord step. This refers to the libolm implementation of Olm. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. Olm N/A
2024-08-22 CVE-2024-45192 An issue was discovered in Matrix libolm through 3.2.16. Cache-timing attacks can occur due to use of base64 when decoding group session keys. This refers to the libolm implementation of Olm. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. Olm N/A
2024-08-22 CVE-2024-45193 An issue was discovered in Matrix libolm through 3.2.16. There is Ed25519 signature malleability due to lack of validation criteria (does not ensure that S < n). This refers to the libolm implementation of Olm. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. Olm N/A
2021-06-16 CVE-2021-34813 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. Olm 9.8
2021-12-14 CVE-2021-44538 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... Cinny, Debian_linux, Element, Javascript_sdk, Olm, Schildichat 9.8
