PHP 5.4.x < 5.4.42 Multiple Vulnerabilities

critical Nessus Plugin ID 84362
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote web server uses a version of PHP that is affected by multiple vulnerabilities.

Description

According to its banner, the version of PHP 5.4.x running on the remote web server is prior to 5.4.42. It is, therefore, affected by multiple vulnerabilities :

- Multiple heap buffer overflow conditions exist in the bundled Perl-Compatible Regular Expression (PCRE) library due to improper validation of user-supplied input to the compile_branch() and pcre_compile2() functions. A remote attacker can exploit these conditions to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-2325, CVE-2015-2326)

- A denial of service vulnerability exists in the bundled SQLite component due to improper handling of quotes in collation sequence names. A remote attacker can exploit this to cause uninitialized memory access, resulting in denial of service condition.
(CVE-2015-3414)

- A denial of service vulnerability exists in the bundled SQLite component due to an improper implementation of comparison operators in the sqlite3VdbeExec() function in vdbe.c. A remote attacker can exploit this to cause an invalid free operation, resulting in a denial of service condition. (CVE-2015-3415)

- A denial of service vulnerability exists in the bundled SQLite component due to improper handling of precision and width values during floating-point conversions in the sqlite3VXPrintf() function in printf.c. A remote attacker can exploit this to cause a stack-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-3416)

- A security bypass vulnerability exists due to a failure in multiple extensions to check for NULL bytes in a path when processing or reading a file. A remote attacker can exploit this, by combining the '\0' character with a safe file extension, to bypass access restrictions.
(CVE-2015-4598)

- An arbitrary command injection vulnerability exists due to a flaw in the php_escape_shell_arg() function in exec.c. A remote attacker can exploit this, via the escapeshellarg() PHP method, to inject arbitrary operating system commands. (CVE-2015-4642)

- A heap buffer overflow condition exists in the ftp_genlist() function in ftp.c. due to improper validation of user-supplied input. A remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2015-4643)
- A denial of service vulnerability exists due to a NULL pointer dereference flaw in the build_tablename() function in pgsql.c. An authenticated, remote attacker can exploit this to cause an application crash.
(CVE-2015-4644)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to PHP version 5.4.42 or later.
