Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 / 9.10 : php5 vulnerabilities (USN-862-1)
high Nessus Plugin ID 42930
Synopsis
The remote Ubuntu host is missing one or more security-related patches.Description
Maksymilian Arciemowicz discovered that PHP did not properly validate arguments to the dba_replace function. If a script passed untrusted input to the dba_replace function, an attacker could truncate the database. This issue only applied to Ubuntu 6.06 LTS, 8.04 LTS, and 8.10. (CVE-2008-7068)It was discovered that PHP's php_openssl_apply_verification_policy function did not correctly handle SSL certificates with zero bytes in the Common Name. A remote attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications. (CVE-2009-3291)
It was discovered that PHP did not properly handle certain malformed images when being parsed by the Exif module. A remote attacker could exploit this flaw and cause the PHP server to crash, resulting in a denial of service. (CVE-2009-3292)
Grzegorz Stachowiak discovered that PHP did not properly enforce restrictions in the tempnam function. An attacker could exploit this issue to bypass safe_mode restrictions. (CVE-2009-3557)
Grzegorz Stachowiak discovered that PHP did not properly enforce restrictions in the posix_mkfifo function. An attacker could exploit this issue to bypass open_basedir restrictions. (CVE-2009-3558)
Bogdan Calin discovered that PHP did not limit the number of temporary files created when handling multipart/form-data POST requests. A remote attacker could exploit this flaw and cause the PHP server to consume all available resources, resulting in a denial of service.
(CVE-2009-4017)
ATTENTION: This update changes previous PHP behaviour by limiting the number of files in a POST request to 50. This may be increased by adding a 'max_file_uploads' directive to the php.ini configuration file.
It was discovered that PHP did not properly enforce restrictions in the proc_open function. An attacker could exploit this issue to bypass safe_mode_protected_env_vars restrictions and possibly execute arbitrary code with application privileges. (CVE-2009-4018).
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.
