The archive_string_append function in archive_string.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (crash) via a crafted cab files, related to "overlapping memcpy."
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.
