Name of the Vulnerable Software and Affected Versions
Open Whisper Signal versions through 2.29.0
Description
The issue arises from the image rendering component, specifically the
createGenericPreview function, which fails to check for unreasonably large images before manipulating them. This allows an attacker to send a large image to a user, causing the device to exhaust its available memory when the image is displayed, resulting in a forced restart.Recommendations
For versions through 2.29.0, as a temporary workaround, consider disabling the image preview feature until a patch is available. Restrict the receipt of large images to minimize the risk of exploitation.
