Ezstream ReplaceString() and urlParse() functions buffer overflow
| ezstream-replacestring-urlparse-bo (32867) |  High Risk |
Description:
Ezstream is vulnerable to multiple buffer overflows, caused by improper bounds checking by the ReplaceString() and urlParse() functions. By persuading a victim to open a specially-crafted XML config file, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash. An attacker could exploit this vulnerability by sending the malicious file to a victim as an email attachment or by hosting it on a Web site.
