========================================================== Ubuntu Security Notice USN-121-1 May 06, 2005 openoffice.org vulnerability CAN-2005-0941 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 4.10 (Warty Warthog) Ubuntu 5.04 (Hoary Hedgehog) The following packages are affected: openoffice.org-bin openoffice.org-l10n-xh The problem can be corrected by upgrading the affected package to version 1.1.2-2ubuntu6.1 (for Ubuntu 4.10 on i386 and powerpc), 1.1.2-2ubuntu6.1-1 (for Ubuntu 4.10 on amd64), 1.1.3-8ubuntu2.3 (for Ubuntu 5.04 on i386 and powerpc), or 1.1.3-8ubuntu2.3-1 (for Ubuntu 5.04 on amd64). In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: The StgCompObjStream::Load() failed to check the validity of a length field in documents. If an attacker tricked a user to open a specially crafted OpenOffice file, this triggered a buffer overflow which could lead to arbitrary code execution with the privileges of the user opening the document. The update for Ubuntu 5.04 (Hoary Hedgehog) also contains a translation update: The "openoffice.org-l10n-xh" package now contains actual Xhosa translations (the previous version just shipped English strings).
