Off-by-one error in the QUtf8Decoder::toUnicode function in Trolltech Qt 3 allows context-dependent attackers to cause a denial of service (crash) via a crafted Unicode string that triggers a heap-based buffer overflow. NOTE: Qt 4 has the same error in the QUtf8Codec::convertToUnicode function, but it is not exploitable.
Multiple format string vulnerabilities in (1) qtextedit.cpp, (2) qdatatable.cpp, (3) qsqldatabase.cpp, (4) qsqlindex.cpp, (5) qsqlrecord.cpp, (6) qglobal.cpp, and (7) qsvgdevice.cpp in QTextEdit in Trolltech Qt 3 before 3.3.8 20070727 allow remote attackers to execute arbitrary code via format string specifiers in text used to compose an error message.
Qt before 3.3.4 searches the BUILD_PREFIX directory, which could be world-writable, to load shared libraries regardless of the LD_LIBRARY_PATH environment variable, which allows local users to execute arbitrary programs.
Heap-based buffer overflow in the BMP image format parser for the QT library (qt3) before 3.3.3 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code.
The XPM parser in the QT library (qt3) before 3.3.3 allows remote attackers to cause a denial of service (application crash) via a malformed image file that triggers a null dereference, a different vulnerability than CVE-2004-0693.
The GIF parser in the QT library (qt3) before 3.3.3 allows remote attackers to cause a denial of service (application crash) via a malformed image file that triggers a null dereference, a different vulnerability than CVE-2004-0692.
