As of today, WinPcap 4.1 beta2 is available in the download section of the WinPcap website, http://www.winpcap.org/install/ . This new software release includes several improvements and changes toboth the library itself and its developer's pack. First of all, it fixes a security vulnerability in the kernel driver reported by the iDefense Labs in the security advisory available at
From the developer's point of view, this version ships with a cleaned
up update of the developer's pack. Some header files that were wronglyincluded in the old developer's pack (including some coming from the Microsoft platform SDK) have been removed. Other files have been consolidated or split into internal header files (used for the build of the binaries) and public header files. Full details can be found in the change log attached at the end of this message. Being a beta release, as usual, we encourage people to test it and report any anomaly or strange behavior to the WinPcap mailing lists. In particular, we strongly encourage all the developers to try compiling all their WinPcap-based applications against the new WinPcap developer's pack and report any compilation issue to the winpcap-bugs mailing list (winpcap-bugs<AT>winpcap.org).
Gianluca Varenni WinPcap Team Changelog from WinPcap 4.0.1 ============================ - Disabled support for monitor mode (also called TME, Table Management Extensions) in the driver. This module suffers from several securityvulnerabilities that could result in BSODs or privilege escalation attacks. This fix addresses a security vulnerability reported by the iDefense Labs at http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=625
- Added a small script to integrate the libpcap sources into the WinPcap tree automatically.
- Moved the definition of all the I/O control codes to ioctls.h. - Cleaned up and removed some build scripts for the developer's pack. - Migrated the driver compilation environment to WDK 6000. - Enabled PreFAST driver compilation for the x64 build.- Added some doxygen directives to group the IOCTL codes and JIT definitions in proper groups.
- Integrated the IOCTL codes into one single set shared by packet.dll and driver.
- Modified the installer to return the win32 error code instead of -1 in case of failure in the error messages.
- Added some #define directives to selectively disable the TME functionality for WAN (i.e. Netmon-assisted) devices.
- Added a VS2005 project to easily edit the files of the driver.- Removed some useless #include directives in the driver and packet.dll.
- Migrated several conditional directives (#ifdef/#endif) to the defines of the DDK/WDK e.g. _X86_ and _AMD64_.
- Added a check to warn users that remote-ext.h should not be included directly. - Removed ntddndis.h from the WinPcap sources. It's included into the Microsoft Platform SDK.- Removed devioctl.h from the WinPcap sources. It's included into the Microsoft DDK/WDK. - Removed ntddpack.h from the WinPcap sources. It's an old header file
from the original DDK Packet sample, and it's not used by WinPcap. - Removed several useless files from the WinPcap developer's pack: + all the TME extension header files + devioctl.h + gnuc.h + ntddndis.h + ntddpack.h + pcap-int.h. - Bug fixing:+ Fixed a possible buffer overrun on x64 machines with more that 32 CPUs/cores.
+ Fixed an implicit cast problem compiling the driver on x64. + Fixed a bug in the installer causing a mis-detection of a previous WinPcap installation.+ Fixed two bugs related to memory deallocation in packet.dll. We were using free() instead of GlobalFreePtr(), and there was a missing check as to when to deallocate a chunk of memory.
+ Added a missing NULL pointer check in pcap_open(). + Moved a misplaced #ifdef WIN32 in pcap_open().+ Fixed a bug in the send routine of the driver that could cause a crash under low resources conditions.
