Descriptions
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.
El plugin del protocolo de Yahoo! en libpurple en Pidgin anterior a 2.10.8 no valida debidamente datos UTF-8, lo que permite a atacantes remotos causar una denegación de servicio (caída de la aplicación) a través de secuencias de bytes manipuladas.
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.
