SCA: security update for org.matrix.android:matrix-android-sdk2 (GHSA-fpgf-pjjv-2qgm)

high Tenable Cloud Security Plugin ID 414611

Description

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

 - matrix-android-sdk2 is the Matrix SDK for Android. Prior to version 1.5.1, an attacker cooperating with a
 malicious homeserver can construct messages that legitimately appear to have come from another person,
 without any indication such as a grey shield. Additionally, a sophisticated attacker cooperating with a
 malicious homeserver could employ this vulnerability to perform a targeted attack in order to send fake
 to-device messages appearing to originate from another user. This can allow, for example, to inject the
 key backup secret during a self-verification, to make a targeted device start using a malicious key backup
 spoofed by the homeserver. matrix-android-sdk2 would then additionally sign such a key backup with its
 device key, spilling trust over to other devices trusting the matrix-android-sdk2 device. These attacks
 are possible due to a protocol confusion vulnerability that accepts to-device messages encrypted with
 Megolm instead of Olm. matrix-android-sdk2 version 1.5.1 has been modified to only accept Olm-encrypted
 to-device messages and to stop signing backups on a successful decryption. Out of caution, several other
 checks have been audited or added. This attack requires coordination between a malicious home server and
 an attacker, so those who trust their home servers do not need a workaround. (CVE-2022-39248)
