In libsndfile before 1.0.28, an error in the "flac_buffer_copy()" function (flac.c) can be exploited to cause a segmentation violation (with write memory access) via a specially crafted FLAC file during a resample attempt, a similar issue to CVE-2017-7585.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
