Ubuntu Security Notice 871-1 – A buffer overflow was found in the KDE libraries when converting a string to a floating point number. If a user or application linked against kdelibs were tricked into processing crafted input, an attacker could cause a denial of service (via application crash) or possibly execute arbitrary code with the privileges of the user invoking the program. It was discovered that the KDE libraries could use KHTML to process an unknown MIME type. If a user or application linked against kdelibs were tricked into opening a crafted file, an attacker could potentially trigger XMLHTTPRequests to remote sites.
