medium Nessus Plugin ID 57315

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

vladz discovered that executables compressed by bzexe insecurely create temporary files when they are ran. A local attacker could exploit this issue to execute arbitrary code as the user running a compressed executable.

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.

Solution

Update the affected bzip2 package.
