Tielei Wang has discovered an integer overflow in wxWidgets, the wxWidgets Cross-platform C++ GUI toolkit, which allows the execution of arbitrary code via a crafted JPEG file. For the oldstable distribution (etch), this problem has been fixed in version 2.4.5.1.1+etch1 for wxwindows2.4 and version 2.6.3.2.1.5+etch1 for wxwidgets2.6. For the stable distribution (lenny), this problem has been fixed in version 2.6.3.2.2-3+lenny1 for wxwidgets2.6 and version 2.8.7.1-1.1+lenny1 for wxwidgets2.8. For the testing distribution (squeeze), this problem will be fixed soon. For the unstable distribution (sid), this problem has been fixed in version 2.8.7.1-2 for wxwidgets2.8 and will be fixed soon for wxwidgets2.6. We recommend that you upgrade your wxwidgets packages.
