Please Install the Updated Packages.
A buffer overflow was found in how Qt expanded malformed Unicode strings. If an application linked against Qt parsed a malicious Unicode string, it could lead to a denial of service or potentially allow for the execution of arbitrary code. Updated packages have been patched to prevent this issue. Although the problem is not exploitable in Qt4, patched packages have been issued regardless.
