Description Matthias Geerdsen (RETIRED) gentoo-dev 2008-05-28 15:02:15 UTC
This bug is marked confidential, do not disclose any information or commit anything until the bug has been made public.

Secunia Research reports a vulnerability in evolution (CVE-2008-{1108,1109}).
Preliminary disclosure date is 2008-06-04 10am CET.

The following is an excerpt from the vulnerability report, more details are

Secunia Research has discovered two vulnerabilities in Evolution, which
can be exploited by malicious people to compromise a user's system.

1) A boundary error exists when parsing timezone strings contained
within iCalendar attachments. This can be exploited to overflow a static
buffer via an overly long timezone string.

Successful exploitation allows execution of arbitrary code, but requires
that the ITip Formatter plugin is disabled.

2) A boundary error exists when replying to an iCalendar request while
in calendar view. This can be exploited to cause a heap-based buffer
overflow via an overly long "DESCRIPTION" property string included in an
iCalendar attachment.

Successful exploitation allows execution of arbitrary code, but requires
that the user accepts the iCalendar request and replies to it from the
"Calendars" window.

The vulnerabilities are confirmed in version 2.22.1. Other versions may
also be affected.

2.22.2 and 2.23.2 are vulnerable.
Comment 4 Robert Buchholz (RETIRED) gentoo-dev 2008-05-31 11:04:11 UTC
I could also reproduce the issue with our stable 2.12.3. I'll attach the patches with clean whitespaces, as the ones above do not apply. If you can, please prepare an ebuild for prestabling.

patch to 2.22.2 ebuild. The first set of patch would need to match the scheme of the second sed of patch to apply properly.
