Ubuntu 4.10 : zip vulnerability (USN-18-1)
Critical Nessus Plugin ID 20590
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionHexView discovered a buffer overflow in the zip package. The overflow is triggered by creating a ZIP archive of files with very long path names. This vulnerability might result in execution of arbitrary code with the privileges of the user who calls zip.
This flaw may lead to privilege escalation on systems which automatically create ZIP archives of user-supplied files, like backup systems or web applications.
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.
SolutionUpdate the affected zip package.
