|pango-harfbuzz-bo (69991)||High Risk|
Pango is vulnerable to a buffer overflow, caused by improper bounds checking by the harfbuzz module in qt. By persuading a victim to visit a specially-crafted Web site, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
Apply the appropriate patch for your system. See References.
