Synopsis |
16 |
======== |
17 |
|
18 |
A stack-based buffer overflow in zoo may be exploited to execute |
19 |
arbitrary code through malicious ZOO archives. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
zoo is a file archiving utility for maintaining collections of files, |
25 |
written by Rahul Dhesi. |
26 |

Affected packages |

Description |
36 |
=========== |
37 |
|
38 |
Jean-Sebastien Guay-Leroux discovered a boundary error in the |
39 |
fullpath() function in misc.c when processing overly long file and |
40 |
directory names in ZOO archives. |
41 |
|
42 |
Impact |
43 |
====== |
44 |
|
45 |
An attacker could craft a malicious ZOO archive and entice someone to |
46 |
open it using zoo. This would trigger a stack-based buffer overflow and |
47 |
potentially allow execution of arbitrary code with the rights of the |
48 |
victim user. |
49 |
|
50 |
Workaround |
51 |
========== |
52 |
|
53 |
There is no known workaround at this time. |
54 |
|
55 |
Resolution |
56 |
========== |
57 |
|
58 |
All zoo users should upgrade to the latest version: |
59 |
|
60 |
# emerge --sync |
61 |
# emerge --ask --oneshot --verbose ">=app-arch/zoo-2.10-r1" |
