Description:
Two vulnerabilities have been reported in CUPS, which can be exploited by malicious, local users to gain knowledge of sensitive information, or by malicious users to bypass certain security restrictions.
1) User credentials are stored in the "error_log" log file when printing to a shared printer via Samba. This discloses user names and passwords to local users.
2) CUPS scheduler uses case-sensitive string comparison on a queue name in "cupsd.conf" to determine how to authenticate a user. However, queue names are not case-sensitive. This can be exploited by unauthorized users to print to a password-protected queue by specifying the queue name using letters in a different case.
