VERIFY ADVISORY:

CRITICAL:
Moderately critical
IMPACT:
DoS, System access
WHERE:
From remote
SOFTWARE:
Pidgin 2.x
link://[click]
DESCRIPTION:
Some vulnerabilities have been reported in Pidgin, which potentially
can be exploited by malicious people to compromise a user's system.
The vulnerabilities are caused due to integer overflow errors in the
"msn_slplink_process_msg" function in
libpurple/protocols/msnp9/slplink.c and
libpurple/protocols/msn/slplink.c, and can potentially be exploited
to execute arbitrary code via a specially crafted SLP message.
Successful exploitation requires that the attacker is allowed to send
messages to a victim (by default only users in the buddy list)
The vulnerability is reported in versions prior to 2.4.3.
SOLUTION:
Update to version 2.4.3.
PROVIDED AND/OR DISCOVERED BY:
Reported via a Red Hat bug report.
