Ubuntu Security Notice USN-871-1

10th December, 2009

kdelibs vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 9.10
  • Ubuntu 9.04
  • Ubuntu 8.10
  • Ubuntu 8.04 LTS

Software description

  • kdelibs


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. (CVE-2009-0689)

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.
