https://notcve.org/view.php?id=CVE-2011-3193
Heap-based buffer overflow in the Lookup_MarkMarkPos function in the HarfBuzz module (harfbuzz-gpos.c), as used by Qt before 4.7.4 and Pango, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted font file. Desbordamiento de buffer de memoria dinámica en la función Lookup_MarkMarkPos del módulo HarfBuzz (harfbuzz-gpos.c), tal como se usa en Qt anteriores a 4.7.4 y Pango. Permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de un archivo de fuentes modificado. • http://cgit.freedesktop.org/harfbuzz.old/commit/?id=81c8ef785b079980ad5b46be4fe7c7bf156dbf65 http://cgit.freedesktop.org/harfbuzz/commit/src/harfbuzz-gpos.c?id=da2c52abcd75d46929b34cad55c4fb2c8892bc08 http://git.gnome.org/browse/pango/commit/pango/opentype/harfbuzz-gpos.c?id=a7a715480db66148b1f487528887508a7991dcd0 http://lists.opensuse.org/opensuse-updates/2011-10/msg00007.html http://lists.opensuse.org/opensuse-updates/2011-10/msg00008.html http://rhn.redhat.com/errata/RHSA-2011-1323.html http://rhn.redhat.com/errata/RH • CWE-787: Out-of-bounds Write •
