タイプ/重大度

Security Advisory: Moderate

トピック

Updated pidgin packages that fix three security issues are now available
for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

説明

Pidgin is an instant messaging program which can log in to multiple
accounts on multiple instant messaging networks simultaneously.

A flaw was found in the way the Pidgin MSN protocol plug-in processed text
that was not encoded in UTF-8. A remote attacker could use this flaw to
crash Pidgin by sending a specially-crafted MSN message. (CVE-2012-1178)

An input validation flaw was found in the way the Pidgin MSN protocol
plug-in handled MSN notification messages. A malicious server or a remote
attacker could use this flaw to crash Pidgin by sending a specially-crafted
MSN notification message. (CVE-2012-2318)

A buffer overflow flaw was found in the Pidgin MXit protocol plug-in. A
remote attacker could use this flaw to crash Pidgin by sending a MXit
message containing specially-crafted emoticon tags. (CVE-2012-3374)

Red Hat would like to thank the Pidgin project for reporting the
CVE-2012-3374 issue. Upstream acknowledges Ulf Harnhammar as the original
reporter of CVE-2012-3374.

All Pidgin users should upgrade to these updated packages, which contain
backported patches to resolve these issues. Pidgin must be restarted for
this update to take effect.
