Debian DLA-850-1 : vim security update

critical Nessus Plugin ID 97641

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Brief introduction

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.

Solution

Upgrade the affected packages.
