CVE-2007-4137

Trolltech Qt 3 - Denial of Service via QUtf8Decoder Heap-Based Buffer Overflow

Title source: llm
STIX 2.1

Description

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.
