1 CVE-2011-0064 DoS Exec Code 2011-03-07 2011-03-30
6.8
 None Remote Medium Not required Partial Partial Partial
The hb_buffer_ensure function in hb-buffer.c in HarfBuzz, as used in Pango 1.28.3, Firefox, and other products, does not verify that memory reallocations succeed, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) or possibly execute arbitrary code via crafted OpenType font data that triggers use of an incorrect index.
2 CVE-2011-0020 119 DoS Exec Code Overflow 2011-01-24 2011-02-04
7.6
 None Remote High Not required Complete Complete Complete
Heap-based buffer overflow in the pango_ft2_font_render_box_glyph function in pango/pangoft2-render.c in libpango in Pango 1.28.3 and earlier, when the FreeType2 backend is enabled, allows user-assisted remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file, related to the glyph box for an FT_Bitmap object.
3 CVE-2010-0421 119 DoS Overflow 2010-03-18 2010-08-21
4.3
 None Remote Medium Not required None None Partial
Array index error in the hb_ot_layout_build_glyph_classes function in pango/opentype/hb-ot-layout.cc in Pango before 1.27.1 allows context-dependent attackers to cause a denial of service (application crash) via a crafted font file, related to building a synthetic Glyph Definition (aka GDEF) table by using this font's charmap and the Unicode property database.
4 CVE-2009-1194 189 DoS Exec Code Overflow 2009-05-11 2010-08-21
6.8
 None Remote Medium Not required Partial Partial Partial
Integer overflow in the pango_glyph_string_set_size function in pango/glyphstring.c in Pango before 1.24 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long glyph string that triggers a heap-based buffer overflow, as demonstrated by a long document.location value in Firefox.
