CVE-2006-7243

Publication date 18 January 2011

Last updated 24 July 2024

Ubuntu priority

PHP before 5.3.4 accepts the \0 character in a pathname, which might allow context-dependent attackers to bypass intended access restrictions by placing a safe file extension after this character, as demonstrated by .php\0.jpg at the end of the argument to the file_exists function.
