GNU Gnash (GNU Flash player) sprite_definition::read() function code execution
| gnuflash-sprite-code-execution (34148) |  High Risk |
Description:
GNU Gnash could allow a remote attacker to execute arbitrary code on the system, caused by a memory corruption vulnerability in the sprite_definition::read() function. By persuading a victim to open a specially-crafted Flash (SWF) file, a remote attacker could exploit this vulnerability to execute arbitrary code on the system or cause the application to crash.
