MiracleLinux 7 : grep-2.20-2.el7 (AXSA:2015-669:01)

medium Nessus Plugin ID 289441

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 7 host has a package installed that is affected by a vulnerability as referenced in the AXSA:2015-669:01 advisory.

 The GNU versions of commonly used grep utilities. Grep searches through textual input for lines which contain a match to a specified pattern and then prints the matching lines. GNU's grep utilities include grep, egrep and fgrep.
 GNU grep is needed by many scripts, so it shall be installed on every system.
 Security issues fixed with this release:
 CVE-2015-1345 The bmexec_trans function in kwset.c in grep 2.19 through 2.21 allows local users to cause a denial of service (out-of-bounds heap read and crash) via crafted input when using the -F option.
 Fixed bugs:
 * Prior to this update, the \w and \W symbols were inconsistently matched to the [:alnum:] character class. Consequently, using regular expressions with \w and \W could lead to incorrect results. With this update, \w is consistently matched to the [_[:alnum:]] character, and \W is consistently matched to the [^_[:alnum:]] character.
 * Previously, the Perl Compatible Regular Expression (PCRE) matcher (selected by the -P parameter in grep) did not work correctly when matching non-UTF-8 text in UTF-8 locales. Consequently, an error message about invalid UTF-8 byte sequence characters was returned. To fix this bug, patches from upstream have been applied to the grep utility. As a result, PCRE now skips non-UTF-8 characters as non-matching text without returning any error message.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected grep package.
