Eric Romang reports a temporary file creation vulnerability within heartbeat. The vulnerability is caused by hard-coded temporary file usage. This can cause an attacker to create an arbitrary symlink causing the application to overwrite the symlinked file with the permissions of the user executing the application.

This advisory adds security support for the stable amd64 distribution.
It covers all security updates since the release of sarge, which were missing updated packages for the not yet official amd64 port. Future security advisories will include updates for this port as well.

Eric Romang discovered that heartbeat created temporary files in an insecure manner. This could allow a symlink attack to create or overwrite arbitrary files with root privileges as soon as heartbeat is started.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

このアドバイザリは、安定版（stable）amd64 ディストリビューションのセキュリティサポートを追加します。
sarge リリース以降のすべてのセキュリティ更新がカバーされます。これには、まだ正式ではない amd64 ポートに対する更新済みパッケージがありませんでした。今後のセキュリティアドバイザリには、このポートの更新も含まれる予定です。

此公告會新增對穩定之 amd64 發行版本的安全性支援。
其中包含自 sarge 發佈以來的所有安全性更新，但缺少非官方 amd64 連接埠的更新版套件。之後的安全性公告也將包含此連接埠的更新。

此公告添加了对稳定 amd64 发行版本的安全支持。
它涵盖自 sarge 发布以来的所有安全更新，该版本缺少针对尚不是官方 amd64 端口的更新后的程序包。未来的安全公告将也包含此端口的更新。

The security update DSA 761-1 for heartbeat contained a bug which caused a regression.  This problem is corrected with this advisory.
 For completeness below please find the original advisory text :

  Eric Romang discovered several insecure temporary file creations in   heartbeat, the subsystem for High-Availability Linux.

The remote host is affected by the vulnerability described in GLSA-200508-05 (Heartbeat: Insecure temporary file creation)

    Eric Romang has discovered that Heartbeat insecurely creates     temporary files with predictable filenames.
  Impact :

    A local attacker could create symbolic links in the temporary file     directory, pointing to a valid file somewhere on the filesystem. When a     vulnerable script is executed, this could lead to the file being     overwritten with the rights of the user running the affected     application.
  Workaround :

    There is no known workaround at this time.
