Improper Link Resolution Before File Access ('Link Following')
master-filter in printfilters-ppd 2.13 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/filter.debug temporary file. NOTE: the vendor disputes this vulnerability, stating 'this package does not have " possibility of attack with the help of symlinks"'
CWE-59 - Improper Link Resolution Before File Access
'Improper link resolution before file access' occurs when software accesses a file resource but fails to verify that the file isn't a link or shortcut to another file. An attacker can potentially gain access to arbitrary files and from there the impact can vary, depending on the application, from sensitive data exposure to remote code execution.
