It was discovered that the sort, uniq, and join utilities did not properly restrict the use of the alloca() function. An attacker could use this flaw to crash those utilities by providing long input strings. (CVE-2013-0221 , CVE-2013-0222 , CVE-2013-0223)

Updated coreutils packages that fix three security issues, several bugs, and add two enhancements are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The coreutils package contains the core GNU utilities. It is a combination of the old GNU fileutils, sh-utils, and textutils packages.

The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2014-028:01 advisory.

    These are the GNU core utilities. This package is the combination of the old GNU fileutils, sh-utils, and     textutils packages.
    Security issues fixed with this release:
     CVE-2013-0221     The SUSE coreutils-i18n.patch for GNU coreutils allows context-dependent attackers to cause a denial of     service (segmentation fault and crash) via a long string to the sort command, when using the (1) -d or (2)
    -M switch, which triggers a stack-based buffer overflow in the alloca function.
     CVE-2013-0222     The SUSE coreutils-i18n.patch for GNU coreutils allows context-dependent attackers to cause a denial of     service (segmentation fault and crash) via a long string to the uniq command, which triggers a stack-based     buffer overflow in the alloca function.
     CVE-2013-0223     The SUSE coreutils-i18n.patch for GNU coreutils allows context-dependent attackers to cause a denial of     service (segmentation fault and crash) via a long string to the join command, when using the -i switch,     which triggers a stack-based buffer overflow in the alloca function.
