Multiple vulnerabilities have been reported in Horde IMP, which can be exploited by malicious people to conduct cross-site scripting and script insertion attacks.
1) Input passed via the 'composeCache', 'rtemode', and 'filename_*' parameters to the compose page and the 'formname' parameter to the contacts popup window is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
2) Certain input via IMAP mailbox names is not properly sanitised before being used. This can be exploited to insert HTML and script code, which will be executed in a user's browser session in context of an affected site if malicious data is viewed.
The vulnerabilities are reported in versions prior to 5.0.18.
Update to version 5.0.18.

Alex/www-apps: Does this affect our IMP H3 packages or only IMP H4?
Multiple cross-site scripting (XSS) vulnerabilities in Horde IMP before
5.0.18 and Horde Groupware Webmail Edition before 4.0.6 allow remote
attackers to inject arbitrary web script or HTML via the (1) composeCache,
(2) rtemode, or (3) filename_* parameters to the compose page; (4) formname
parameter to the contacts popup window; or (5) IMAP mailbox names. NOTE:
some of these details are obtained from third party information.
@maintainers: Any plans for bumping this package to a version not vulnerable?
still no bump from maintainer(s). only dependency is www-apps/horde-dimp which has been integrated to >=horde-imp-5.0 upstream. candidate for tree cleaning along with horde-dimp
# Aaron Bauman <email@example.com> (05 Mar 2016)
# Per security bug #399563 these packages are vulnerable
# and unmaintained. Removal in 30 days.
Masking horde means masking its extensions as well, namely this list of packages:
monsieurp@epsilon ~/gentoo $ printf '%s\n' www-apps/horde*
www-apps/horde was not masked. Two of the extensions were per previous mask message.
