Pango pango_glyph_string_set_size() buffer overflow
| pango-pangoglyphstringsetsize-bo (50397) |  High Risk |
Description:
Pango is vulnerable to a heap-based buffer overflow, caused by an integer overflow in the pango_glyph_string_set_size() function. By sending a text with overly long glyph strings, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
