Description
A use-after-free issue has been found in libarchive >= 3.1.0 and <=3.3.3, in the archive_read_format_rar_read_header() function in archive_read_support_format_rar.c. An attacker can use a specially crafted RAR file to cause the vulnerable function to free the buffer and allocate a new one, causing the ppmd7 decoder to continue reading from and writing to the freed buffer.
