file does not properly restrict the amount of data read during a regex search, which allows remote attackers to cause a denial of service (CPU consumption).

CVE-2014-3587

Integer overflow in the cdf_read_property_info function in cdf.c allows remote attackers to cause a denial of service (application crash).

Note: The other seven issues for wheezy, fixed in 5.11-2+deb7u4 (DSA-3021-1), were already handled in 5.04-5+squeeze6 (DLA 27-1) in July 2014. Also, as an amendment, as a side effect of the changes done back then, the MIME type detection of some files had improved from 'application/octet-stream' to something more specific like 'application/x-dosexec' or 'application/x-iso9660-image'.

For Debian 6 Squeeze, these issues have been fixed in file version 5.04-5+squeeze7");
