CVE-2019-17192
Last modified
CVE-2019-17192 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. The WebRTC component in the Signal Private Messenger application through 4.47.7 for Android processes videoconferencing RTP packets before a callee chooses to answer a call, which might make it easier for remote attackers to cause a denial of service or possibly have unspecified other impact via malformed packets. NOTE: the vendor plans to continue this behavior for performance reasons unless a WebRTC design change occurs. EPSS estimates a 2.73% chance of exploitation in the next 30 days.
