Références of this alert: BID-48073, c03216705, CVE-2011-2328, HPSBMU02785, SSRT100526, VIGILANCE-VUL-10721, VU#987308.

Description of the vulnerability

The HP LoadRunner product simulates users (Virtual User) in order to test an application under load.

Virtual Users are defined in a file with the ".usr" extension. The Vuser User Generator (VuGen.exe) application is called to open ".usr" files. However, when directives in a ".usr" file are too long, a buffer overflow occurs in VuGen.exe.

An attacker can therefore create a malicious Virtual User file, in order to create a buffer overflow in HP LoadRunner, and to execute code.
