Descriptions

A use-after-free vulnerability exists in the HTTP Connection Headers parsing in Tinyproxy 1.11.1 and Tinyproxy 1.10.0. A specially crafted HTTP header can trigger reuse of previously freed memory, which leads to memory corruption and could lead to remote code execution. An attacker needs to make an unauthenticated HTTP request to trigger this vulnerability.

Existe una vulnerabilidad de use-after-free en el análisis de los encabezados de conexión HTTP en Tinyproxy 1.11.1 y Tinyproxy 1.10.0. Un encabezado HTTP especialmente manipulado puede provocar la reutilización de la memoria previamente liberada, lo que provoca daños en la memoria y podría provocar la ejecución remota de código. Un atacante necesita realizar una solicitud HTTP no autenticada para activar esta vulnerabilidad.
