Título:	RedHat Update for grep RHSA-2015:2111-07
Resumen:	The remote host is missing an update for the 'grep'; package(s) announced via the referenced advisory.
Descripción:	Summary: The remote host is missing an update for the 'grep' package(s) announced via the referenced advisory. Vulnerability Insight: The grep utility searches through textual input for lines that contain a match to a specified pattern and then prints the matching lines. The GNU grep utilities include grep, egrep, and fgrep. A heap-based buffer overflow flaw was found in the way grep processed certain pattern and text combinations. An attacker able to trick a user into running grep on specially crafted input could use this flaw to crash grep or, potentially, read from uninitialized memory. (CVE-2015-1345) This update also fixes the following 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. (BZ#1159012) * 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. (BZ#1217080) All grep users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. Affected Software/OS: grep on Red Hat Enterprise Linux Server (v. 7) Solution: Please Install the Updated Packages. CVSS Score: 2.1 CVSS Vector: AV:L/AC:L/Au:N/C:N/I:N/A:P
