CVE-2017-6349

An integer overflow at a u_read_undo memory allocation site would
occur for vim before patch 8.0.0377, if it does not properly validate
values for tree length when reading a corrupted undo file, which may
lead to resultant buffer overflows.

CVE-2017-6350

An integer overflow at an unserialize_uep memory allocation site would
occur for vim before patch 8.0.0378, if it does not properly validate
values for tree length when reading a corrupted undo file, which may
lead to resultant buffer overflows.

For Debian 7 'Wheezy', these problems have been fixed in version
2:7.3.547-7+deb7u3.

We recommend that you upgrade your vim 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."
