Descriptions

Multiple integer overflows in libssh before 0.5.3 allow remote attackers to cause a denial of service (infinite loop or crash) and possibly execute arbitrary code via unspecified vectors, which triggers a buffer overflow, infinite loop, or possibly some other unspecified vulnerabilities.

Múltiples desbordamientos de enteros en libssh antes de v0.5.3 permiten a atacantes remotos provocar una denegación de servicio (bucle infinito o caída) y posiblemente ejecutar código de su elección a través de vectores no especificados, lo que provoca un desbordamiento de búfer, bucle infinito, o posiblemente algunas vulnerabilidades no especificadas.
