CVE-2016-3959 – golang: infinite loop in several big integer routines

https://notcve.org/view.php?id=CVE-2016-3959

The Verify function in crypto/dsa/dsa.go in Go before 1.5.4 and 1.6.x before 1.6.1 does not properly check parameters passed to the big integer library, which might allow remote attackers to cause a denial of service (infinite loop) via a crafted public key to a program that uses HTTPS client certificates or SSH server libraries. La función Verify en crypto/dsa/dsa.go en Go en versiones anteriores a 1.5.4 y 1.6.x en versiones anteriores a 1.6.1 no comprueba correctamente los parámetros pasados a la gran librería de entero, lo que podría permitir a atacantes remotos provocar una denegación de servicio (bucle infinito) a través de una clave pública manipulada a un programa que usa certificados de clientes HTTPS o servidores de librerías SSH. A denial of service vulnerability was found in Go's verification of DSA public keys. An attacker could provide a crafted key to HTTPS client or SSH server libraries which would cause the application to enter an infinite loop. • http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182526.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/183106.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/183137.html http://lists.opensuse.org/opensuse-updates/2016-05/msg00077.html http://rhn.redhat.com/errata/RHSA-2016-1538.html http://www.openwall.com/lists/oss-security/2016/04/05/1 http://www.openwall.com/lists/oss-security/2016/04/05/2 https://go-review& • CWE-20: Improper Input Validation CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
