Описание:Переполнение буфера при разборе протокола Gadu-Gadu. DoS при разборе протоколов Yahoo!, XMPP, MSN, HTTP, STUN, IRC, обработке URL, повреждение памяти при обработке HTTP, эмотиконов MXit, SIMPLE.
Затронутые продукты:PIDGIN : Pidgin 2.10
 LIBGADU : libgadu 1.11
CVE:CVE-2014-0020 (The IRC protocol plugin in libpurple in Pidgin before 2.10.8 does not validate argument counts, which allows remote IRC servers to cause a denial of service (application crash) via a crafted message.)
 CVE-2013-6490 (The SIMPLE protocol functionality in Pidgin before 2.10.8 allows remote attackers to have an unspecified impact via a negative Content-Length header, which triggers a buffer overflow.)
 CVE-2013-6489 (Integer signedness error in the MXit functionality in Pidgin before 2.10.8 allows remote attackers to cause a denial of service (segmentation fault) via a crafted emoticon value, which triggers an integer overflow and a buffer overflow.)
 CVE-2013-6487 (Integer overflow in libpurple/protocols/gg/lib/http.c in the Gadu-Gadu (gg) parser in Pidgin before 2.10.8 allows remote attackers to have an unspecified impact via a large Content-Length value, which triggers a buffer overflow.)
 CVE-2013-6485 (Buffer overflow in util.c in libpurple in Pidgin before 2.10.8 allows remote HTTP servers to cause a denial of service (application crash) or possibly have unspecified other impact via an invalid chunk-size field in chunked transfer-coding data.)
 CVE-2013-6484 (The STUN protocol implementation in libpurple in Pidgin before 2.10.8 allows remote STUN servers to cause a denial of service (out-of-bounds write operation and application crash) by triggering a socket read error.)
 CVE-2013-6483 (The XMPP protocol plugin in libpurple in Pidgin before 2.10.8 does not properly determine whether the from address in an iq reply is consistent with the to address in an iq request, which allows remote attackers to spoof iq traffic or cause a denial of service (NULL pointer dereference and application crash) via a crafted reply.)
 CVE-2013-6482 (Pidgin before 2.10.8 allows remote MSN servers to cause a denial of service (NULL pointer dereference and crash) via a crafted (1) SOAP response, (2) OIM XML response, or (3) Content-Length header.)
 CVE-2013-6481 (libpurple/protocols/yahoo/libymsg.c in Pidgin before 2.10.8 allows remote attackers to cause a denial of service (crash) via a Yahoo! P2P message with a crafted length field, which triggers a buffer over-read.)
 CVE-2013-6479 (util.c in libpurple in Pidgin before 2.10.8 does not properly allocate memory for HTTP responses that are inconsistent with the Content-Length header, which allows remote HTTP servers to cause a denial of service (application crash) via a crafted response.)
 CVE-2013-6478 (gtkimhtml.c in Pidgin before 2.10.8 does not properly interact with underlying library support for wide Pango layouts, which allows user-assisted remote attackers to cause a denial of service (application crash) via a long URL that is examined with a tooltip.)
 CVE-2013-6477 (Multiple integer signedness errors in libpurple in Pidgin before 2.10.8 allow remote attackers to cause a denial of service (application crash) via a crafted timestamp value in an XMPP message.)
 CVE-2012-6152 (The Yahoo! protocol plugin in libpurple in Pidgin before 2.10.8 does not properly validate UTF-8 data, which allows remote attackers to cause a denial of service (application crash) via crafted byte sequences.)
