Summary

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.
