Synopsis |
16 |
======== |
17 |
|
18 |
The Safe module for Perl does not properly restrict code, allowing a |
19 |
remote attacker to execute arbitrary Perl code outside of a restricted |
20 |
compartment. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|
25 |
Safe is a Perl module to compile and execute code in restricted |
26 |
compartments. |
27 |
|
28 |

Description |
41 |
=========== |
42 |
|
43 |
Unsafe code evaluation prevents the Safe module from properly |
44 |
restricting the code of implicitly called methods on implicitly blessed |
45 |
objects. |
46 |
|
47 |
Impact |
48 |
====== |
49 |
|
50 |
A remote attacker could entice a user to load a specially crafted Perl |
51 |
script, resulting in execution arbitrary Perl code outside of a |
52 |
restricted compartment. |
53 |
|
54 |
Workaround |
55 |
========== |
56 |
|
57 |
There is no known workaround at this time. |
58 |
|
59 |
Resolution |
60 |
========== |
61 |
|
62 |
All users of the standalone Perl Safe module should upgrade to the |
63 |
latest version: |
64 |
|
65 |
# emerge --sync |
66 |
# emerge --ask --oneshot --verbose ">=perl-core/Safe-2.27" |
67 |
|
68 |
All users of the Safe module bundled with Perl should upgrade to the |
69 |
latest version: |
70 |
|
71 |
# emerge --sync |
72 |
# emerge --ask --oneshot --verbose ">=virtual/perl-Safe-2.27" |
73 |
|

NOTE: This is a legacy GLSA. Updates for all affected architectures are |
75 |
available since July 18, 2010. It is likely that your system is already |
76 |
no longer affected by this issue. |
