Summary
mackron / dr_libs dr_wav.h Heap Buffer Overflow via WAV File
Details

drlibs drwav.h version 0.14.4 and earlier (fixed in commit 8a7258c) contain a heap buffer overflow vulnerability in the drwav_readsmpltometadataobj() function of drwav.h that allows memory corruption via crafted WAV files. Attackers can exploit a mismatch between sampleLoopCount validation in pass 1 and unconditional processing in pass 2 to overflow heap allocations with 36 bytes of attacker-controlled data through any drwavinit*withmetadata() call on untrusted input.
