The remote host is affected by the vulnerability described in GLSA-200901-13 (Pidgin: Multiple vulnerabilities)
Multiple vulnerabilities have been discovered in Pidgin and the libpurple library:
A participant to the TippingPoint ZDI reported multiple integer overflows in the msn_slplink_process_msg() function in the MSN protocol implementation (CVE-2008-2927).
Juan Pablo Lopez Yacubian is credited for reporting a use-after-free flaw in msn_slplink_process_msg() in the MSN protocol implementation (CVE-2008-2955).
The included UPnP server does not limit the size of data to be downloaded for UPnP service discovery, according to a report by Andrew Hunt and Christian Grothoff (CVE-2008-2957).
Josh Triplett discovered that the NSS plugin for libpurple does not properly verify SSL certificates (CVE-2008-3532).
Impact :
A remote attacker could send specially crafted messages or files using the MSN protocol which could result in the execution of arbitrary code or crash Pidgin. NOTE: Successful exploitation might require the victim's interaction. Furthermore, an attacker could conduct man-in-the-middle attacks to obtain sensitive information using bad certificates and cause memory and disk resources to exhaust.
Workaround :
There is no known workaround at this time.
