Synopsis |
16 |
======== |
17 |
|
18 |
Bugzilla contains several vulnerabilities, some of them possibly |
19 |
leading to the remote execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Bugzilla is a web application designed to help with managing software |
25 |
development. |

Description |
38 |
=========== |
39 |
|
40 |
Masahiro Yamada found that from the 2.17.1 version, Bugzilla does not |
41 |
properly sanitize the content of the "buildid" parameter when filing |
42 |
bugs (CVE-2007-4543). The next two vulnerabilities only affect Bugzilla |
43 |
2.23.3 or later, hence the stable Gentoo Portage tree does not contain |
44 |
these two vulnerabilities: Loic Minier reported that the |
45 |
"Email::Send::Sendmail()" function does not properly sanitise "from" |
46 |
email information before sending it to the "-f" parameter of |
47 |
/usr/sbin/sendmail (CVE-2007-4538), and Frédéric Buclin discovered |
48 |
that the XML-RPC interface does not correctly check permissions in the |
49 |
time-tracking fields (CVE-2007-4539). |
50 |
|
51 |
Impact |
52 |
====== |
53 |
|
54 |
A remote attacker could trigger the "buildid" vulnerability by sending |
55 |
a specially crafted form to Bugzilla, leading to a persistent XSS, thus |
56 |
allowing for theft of credentials. With Bugzilla 2.23.3 or later, an |
57 |
attacker could also execute arbitrary code with the permissions of the |
58 |
web server by injecting a specially crafted "from" email address and |
59 |
gain access to normally restricted time-tracking information through |
60 |
the XML-RPC service. |
61 |
|
62 |
Workaround |
63 |
========== |
64 |
|
65 |
There is no known workaround at this time. |
66 |
|
67 |
Resolution |
68 |
========== |
69 |
|
70 |
All Bugzilla users should upgrade to the latest version: |
71 |
|
72 |
# emerge --sync |
73 |
# emerge --ask --oneshot --verbose www-apps/bugzilla |
74 |
