Description

CVE-2014-3538

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 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'.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
