The posix_mkfifo function in ext/posix/posix.c in PHP before 5.2.12 and 5.3.x before 5.3.1 allows context-dependent attackers to bypass open_basedir restrictions, and create FIFO files, via the pathname and mode arguments, as demonstrated by creating a .htaccess file.

The tempnam function in ext/standard/file.c in PHP before 5.2.12 and 5.3.x before 5.3.1 allows context-dependent attackers to bypass safe_mode restrictions, and create files in group-writable or world-writable directories, via the dir and prefix arguments.

The php_openssl_apply_verification_policy function in PHP before 5.2.11 does not properly perform certificate validation, which has unknown impact and attack vectors, probably related to an ability to spoof certificates.

Unspecified vulnerability in PHP before 5.2.11, and 5.3.x before 5.3.1, has unknown impact and attack vectors related to "missing sanity checks around exif processing."

Unspecified vulnerability in the imagecolortransparent function in PHP before 5.2.11 has unknown impact and attack vectors related to an incorrect "sanity check for the color index."

Cross-site scripting (XSS) vulnerability in PHP, possibly 5.2.7 and earlier, when display_errors is enabled, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. NOTE: because of the lack of details, it is unclear whether this is related to CVE-2006-0208.

Stack-based buffer overflow in apc.c in Alternative PHP Cache (APC) 3.0.11 through 3.0.16 allows remote attackers to execute arbitrary code via a long filename.

The session extension in PHP before 5.2.4 might allow local users to bypass open_basedir restrictions via a session file that is a symlink.

Integer overflow in the zip_read_entry function in PHP 4 before 4.4.5 allows remote attackers to execute arbitrary code via a ZIP archive that contains an entry with a length value of 0xffffffff, which is incremented before use in an emalloc call, triggering a heap overflow.

The compress.bzip2:// URL wrapper provided by the bz2 extension in PHP before 4.4.7, and 5.x before 5.2.2, does not implement safemode or open_basedir checks, which allows remote attackers to read bzip2 archives located outside of the intended directories.
