Kitty is a cross-platform GPU based terminal. Versions 0.46.2 and below contain a heap buffer overflow in load_image_data() that allows any process which can write to the terminal's stdin to crash kitty immediately. The vulnerability is triggered by a single APC graphics protocol command with a PNG format declaration (f=100) whose payload exceeds twice the initial buffer capacity. The overflow is attacker-controlled in both length and content, causing DoS and potentially escalation to RCE itself. This issue has been fixed in version 0.47.0.

Heap buffer overflow in Kitty terminal versions 0.46.2 and below allows any process able to write to the terminal's standard input to crash the application and potentially achieve remote code execution. The flaw lives in load_image_data() and is triggered by a single APC graphics protocol command declaring PNG format (f=100) with a payload exceeding twice the initial buffer capacity, giving the attacker control over both overflow length and content. …
