Scroller Ubuntu
Security flaws in CUPS on Ubuntu may lead to unauthorized access to confidential information, potentially enabling privilege elevation and increased vulnerability.
CUPS could be made to expose sensitive information, leading to privilege escalation.

Summary

CUPS could be made to expose sensitive information, leading to privilege

escalation.

Software Description:

- cups: Common UNIX Printing System(tm)

Details:

Salvatore Bonaccorso discovered that the CUPS web interface incorrectly

validated permissions and incorrectly handled symlinks. An attacker could

possibly use this issue to bypass file permissions and read arbitrary

files, possibly leading to a privilege escalation.
