Description
smallbitvec is a growable bit-vector for Rust, optimized for size. From 1.0.1 to 2.6.0, an integer overflow in the internal capacity calculation of smallbitvec can lead to an undersized heap allocation, resulting in a heap buffer overflow through safe APIs only. This allows memory corruption without requiring unsafe code from the caller. This vulnerability is fixed in 2.6.1.

Title: smallbitvec de servo, Description: smallbitvec es un vector de bits redimensionable para Rust, optimizado para el tamaño. De 1.0.1 a 2.6.0, un desbordamiento de entero en el cálculo interno de capacidad de smallbitvec puede conducir a una asignación de memoria en el heap de tamaño insuficiente, lo que resulta en un desbordamiento de búfer en el heap únicamente a través de APIs seguras. Esto permite la corrupción de memoria sin requerir código inseguro por parte del llamador. Esta vulnerabilidad está corregida en 2.6.1.
