CVE-2008-5243 is a medium-severity flaw (CVSS 4.3) affecting xine-lib. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- No elevated risk signals yet
A fixed release or distro patch exists.
