Descriptions

In FreeBSD 12.1-STABLE before r357213, 12.1-RELEASE before 12.1-RELEASE-p2, 12.0-RELEASE before 12.0-RELEASE-p13, 11.3-STABLE before r357214, and 11.3-RELEASE before 11.3-RELEASE-p6, URL handling in libfetch with URLs containing username and/or password components is vulnerable to a heap buffer overflow allowing program misbehavior or malicious code execution.

En FreeBSD versiones 12.1-STABLE anteriores a r357213, versiones 12.1-RELEASE versiones anteriores a 12.1-RELEASE-p2, versiones 12.0-RELEASE anteriores a 12.0-RELEASE-p13, versiones 11.3-STABLE anteriores a r357214 y versiones 11.3-RELEASE anteriores a 11.3-RELEASE-p6, el manejo de URL en libfetch con URLs que contienen componentes de nombre de usuario y/o contraseña es vulnerable a un desbordamiento del búfer, que permite un comportamiento inapropiado del programa o una ejecución de código malicioso.
