{ "url": "http://public2.vulnerablecode.io/api/vulnerabilities/74779?format=api", "vulnerability_id": "VCID-rbtm-8gfk-sfb8", "summary": "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.", "aliases": [ { "alias": "CVE-2026-33633" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/509781?format=api", "purl":
