SUSE-SA:2003:002: cups |
||
Check for the version of the cups package Detailed Explanation for this Vulnerability Assessment The remote host is missing the patch for the advisory SUSE-SA:2003:002 (cups). CUPS is a well documented and widely used printing system for unix-like systems. iDFENSE reported several security issues with CUPS that can lead to local and remote root compromise. The following list includes all vulnerabilities: - integer overflow in HTTP interface to gain remote access with CUPS rights - local file race condition to gain root (bug mentioned above has to be exploited first) - remotely add printers - remote denial-of-service attack due to negative length in memcpy() call - integer overflow in image handling code to gain higher rights - gain local root due to buffer overflow of 'options' buffer - design problem to gain local root (needs added printer, see above) - wrong handling of zero width images can be abused to gain higher rights - file descriptor leak and denial-of-service due to missing checks of return values of file/socket operations Since SUSE 8.1 CUPS is the default printing system. As a temporary workaround CUPS can be disabled and an alternative printing system like LPRng can be installed instead. New CUPS packages are available on our FTP servers. Please, install them to fix your system. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command 'rpm -Fhv file.rpm' to apply the update.
