CVE-2015-1858: Qt before 4.8.7/5.4.2 can crash or run code
CVE-2015-1858 · published 11 years ago
Summary
The Qt graphics library versions prior to 4.8.7 and 5.4.2 have a weakness in the code that processes BMP image files. An attacker who sends a specially crafted BMP image can cause the application to stop working or, in rare cases, execute unwanted commands. Update Qt to the latest version or apply the vendor's patch to eliminate the risk.

Multiple buffer overflows in gui/image/qbmphandler.cpp in the QtBase module in Qt before 4.8.7 and 5.x before 5.4.2 allow remote attackers to cause a denial of service (segmentation fault and crash) and possibly execute arbitrary code via a crafted BMP image.
