Stack-based buffer overflow in mchan.dll in the agent in HPE LoadRunner 11.52 through patch 3, 12.00 through patch 1, 12.01 through patch 3, 12.02 through patch 2, and 12.50 through patch 3 and Performance Center 11.52 through patch 3, 12.00 through patch 1, 12.01 through patch 3, 12.20 through patch 2, and 12.50 through patch 1 allows remote attackers to execute arbitrary code via a long -server_name value, aka ZDI-CAN-3516.

The version of HP Performance Center installed on the remote Windows host is 11.52.x or 12.x prior to 12.53. It is, therefore, affected by multiple vulnerabilities :

  - An overflow condition exists in mchan.dll due to a     failure to validate the size of a user-supplied string     prior to copying it to a stack-based buffer. An     unauthenticated, remote attacker can exploit this to     cause a stack-based buffer overflow, resulting in the     execution of arbitrary code. (CVE-2016-4359)   
  - A flaw exists in the CSV import feature when handling     file paths. An unauthenticated, remote attacker can     exploit this to delete arbitrary files on the remote     system. (CVE-2016-4360)   
  - A flaw exists in the magentservice.exe service that is     triggered when handling malformed xdr_string fields in a     series of service connection requests. An     unauthenticated, remote attacker can exploit this, via a     specially crafted request, to crash the service,     resulting in a denial of service condition.
    (CVE-2016-4361)

  - A flaw exists in the mchan.dll library due to improper     parsing of malformed packets. An unauthenticated, remote     attacker can exploit this, via a specially crafted     request, to crash the service, resulting in a denial of     service condition. (CVE-2016-4384)

The Hewlett Packard Enterprise (HPE) LoadRunner application running on the remote host is affected by a stack-based buffer overflow condition in mchan.dll, when constructing a shared memory file name, due to improper validation of the size of a user-supplied string. An unauthenticated, remote attacker can exploit this, via a long '-server_name' value, to execute arbitrary code with the privileges of the user running the application.

Note that LoadRunner reportedly is affected by other vulnerabilities, which can result in a denial of service; however, Nessus has not tested for these.

The version of HP LoadRunner installed on the remote Windows host is 11.52, 12.00, 12.01, 12.02, or 12.50, without the HPSBGN03609 hotfix.
