CVE-2011-3594
Estado: ModificadaMedia (4.3)—
The g_markup_escape_text function in the SILC protocol plug-in in libpurple 2.10.0 and earlier, as used in Pidgin and possibly other products, allows remote attackers to cause a denial of service (crash) via invalid UTF-8 sequences that trigger use of invalid pointers and an out-of-bounds read, related to interactions with certain versions of glib2.
CVSS
- Versión: 2.0
- Vector: AV:N/AC:M/Au:N/C:N/I:N/A:P
