| 45 |
Tavis Ormandy and Will Drewry (Google Security Team) discovered a |
| 46 |
heap-based buffer overflow in the Regular Expression engine (regcomp.c) |
| 47 |
that occurs when switching from byte to Unicode (UTF-8) characters in a |
| 48 |
regular expression. |

<impact type="normal"> |
| 52 |
<p> |
| 53 |
A remote attacker could either entice a user to compile a specially |
| 54 |
crafted regular expression or actively compile it in case the script |
| 55 |
accepts remote input of regular expressions, possibly leading to the |
| 56 |
execution of arbitrary code with the privileges of the user running |
| 57 |
Perl. |
| 58 |
</p> |
| 59 |
</impact> |
| 60 |
<workaround> |
| 61 |
<p> |
| 62 |
There is no known workaround at this time. |
| 63 |

<resolution> |
| 66 |
<p> |
| 67 |
All Perl users should upgrade to the latest version: |
| 68 |
</p> |

<code> |
| 70 |
# emerge --sync |
| 71 |
# emerge --ask --oneshot --verbose ">=dev-lang/perl-5.8.8-r4"</code> |
