CVE-2018-18584 Fixing the size of the CAB block input buffer, which is too small for the maximal Quantum block, prevents an out-of-bounds write.
CVE-2018-18585 Blank filenames (having length zero or their 1st or 2nd byte is null) should be rejected.
For Debian 8 ‘Jessie’, these problems have been fixed in version 0.5-1+deb8u3.
We recommend that you upgrade your libmspack packages.
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.
