NVD Description

See How to fix? for Debian:14 relevant fixed versions and status.
Thor Vector Graphics (ThorVG) is a production-ready vector graphics engine. Prior to 1.0.7, the SFNT/TTF font loader's SfntLoader::gen function in tvgSfntLoader.cpp reads data[0] through data[3] to identify the font type without first checking that the input buffer contains at least four bytes. Loading an undersized font directly from memory through public APIs such as tvg::Text::load causes an out-of-bounds read. Loading through a file path using mmap can mask the read because of page alignment; the memory-loading API directly exposes it. Depending on memory layout, a malformed short font may crash the consuming application or disclose adjacent heap memory. This issue is fixed in version 1.0.7.
