Descriptions

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.

Error de signo de enteros en la funcionalidad MXit en Pidgin anterior a 2.10.8 permite a atacantes remotos causar una denegación de servicio (fallo de segmentación) a través de un valor manipulado de emoticono, lo que provoca un desbordamiento de entero y desbordamiento de buffer.

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 via crafted byte sequences. Multiple integer signedness errors in libpurple in Pidgin before 2.10.8 allow remote attackers to cause a denial of service via a crafted timestamp value in an XMPP message. 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 via a long URL that is examined with a tooltip. 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 via a crafted response. Various other issues were also addressed.
