Description

This security bulletin contains information about 3 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2012-0788)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Green


The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The PDORow implementation in PHP before 5.3.9 does not properly interact with the session feature, which allows remote attackers to cause a denial of service (application crash) via a crafted application that uses a PDO driver for a fetch and then calls the session_start function, as demonstrated by a crash of the Apache HTTP Server.


2) Memory leak (CVE-ID: CVE-2012-0789)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to memory leak within the timezone functionality in PHP before 5.3.9 allows remote attackers to cause a denial of service (memory consumption) by triggering many strtotime function calls, which are not properly handled by the php_date_parse_tzfile cache. A remote attacker can perform a denial of service attack.


3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-0057)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

PHP before 5.3.9 has improper libxslt security settings, which allows remote attackers to create arbitrary files via a crafted XSLT stylesheet that uses the libxslt output extension.
