UnZip inflate_dynamic() code execution
| unzip-inflatedynamic-code-execution (41246) |  High Risk |
Description:
UnZip could allow a remote attacker to execute arbitrary code on the system, caused by the passing of uninitialized pointers in the inflate_dynamic() function. A remote attacker could exploit this vulnerability using a specially-crafted ZIP file to release a restricted memory region and execute arbitrary code on the system.
