Descriptions

Buffer Overflow in uudecoder in Mutt affecting all versions starting from 0.94.13 before 2.2.3 allows read past end of input line

Un Desbordamiento del Búfer en uudecoder en Mutt afectando a todas las versiones a partir de 0.94.13 antes de 2.2.3 permite leer más allá del final de la línea de entrada

A flaw was found in mutt. When reading unencoded messages, mutt uses the line length from the untrusted input without any validation. This flaw allows an attacker to craft a malicious message, which leads to an out-of-bounds read, causing data leaks that include fragments of other unrelated messages.

It was discovered that Mutt incorrectly handled certain requests. An attacker could possibly use this issue to expose sensitive information. This issue only affected Ubuntu 20.04 LTS. It was discovered that Mutt incorrectly handled certain input. An attacker could possibly use this issue to cause a crash, or expose sensitive information.
