Nikolaus Schulz discovered that a programming error in id3lib, an ID3 Tag Library, may lead to denial of service through symlink attacks. For the oldstable distribution (sarge) this problem has been fixed in version 3.8.3-4.1sarge1. Due to a technical limitation in the archive management scripts the fix for the stable distribution (etch) can only be released in a few days. For the unstable distribution (sid) this problem has been fixed in version 3.8.3-7. We recommend that you upgrade your id3lib3.8.3 packages.
