Key facts

Description

The real_parse_headers function in demux_real.c in xine-lib 1.1.12, and other 1.1.15 and earlier versions, relies on an untrusted input length value to "reindex into an allocated buffer," which allows remote attackers to cause a denial of service (crash) via a crafted value, probably an array index error.
