Ubuntu 5.04 / 5.10 / 6.06 LTS : php4, php5 vulnerabilities (USN-362-1)

Critical Nessus Plugin ID 27942

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 6.7

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

The stripos() function did not check for invalidly long or empty haystack strings. In an application that uses this function on arbitrary untrusted data this could be exploited to crash the PHP interpreter. (CVE-2006-4485)

An integer overflow was discovered in the PHP memory allocation handling. On 64-bit platforms, the 'memory_limit' setting was not enforced correctly. A remote attacker could exploit this to cause a Denial of Service attack through memory exhaustion. (CVE-2006-4486)

Maksymilian Arciemowicz discovered that security relevant configuration options like open_basedir and safe_mode (which can be configured in Apache's httpd.conf) could be bypassed and reset to their default value in php.ini by using the ini_restore() function.
(CVE-2006-4625)

Stefan Esser discovered that the ecalloc() function in the Zend engine did not check for integer overflows. This particularly affected the unserialize() function. In applications which unserialize untrusted user-defined data, this could be exploited to execute arbitrary code with the application's privileges. (CVE-2006-4812).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
