CVE-2019-3563 is a vulnerability in Facebook Wangle
Published on April 29, 2019
Wangle's LineBasedFrameDecoder contains logic for identifying newlines which incorrectly advances a buffer, leading to a potential underflow. This affects versions of Wangle prior to v2019.04.22.00
Weakness Type
Buffer Over-read
The software reads from a buffer using buffer access mechanisms such as indexes or pointers that reference memory locations after the targeted buffer. This typically occurs when the pointer or its index is incremented to a position beyond the bounds of the buffer or when pointer arithmetic results in a position outside of the valid memory location to name a few. This may result in exposure of sensitive information or possibly a crash.
