Descriptions

Heap-based buffer overflow in CVS 1.11.x up to 1.11.15, and 1.12.x up to 1.12.7, when using the pserver mechanism allows remote attackers to execute arbitrary code via Entry lines.

Desbordamiento basado en la pila en CVS 1.11.X a 1.11.5 y 1.12. a 1.12.7, cuando se usa el mecanismo pserver, permite a atacantes remotos ejecutar código arbitrario mediante lineas de Entradas.

Stable CVS releases up to 1.11.15 and CVS feature releases up to 1.12.7 both contain a flaw when deciding if a CVS entry line should get a modified or unchanged flag attached. This results in a heap overflow which can be exploited to execute arbitrary code on the CVS server. This could allow a repository compromise.
