Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-99-1)
Summary:	The remote host is missing an update for the 'php4' package(s) announced via the USN-99-1 advisory.
Description:	Summary: The remote host is missing an update for the 'php4' package(s) announced via the USN-99-1 advisory. Vulnerability Insight: Stefano Di Paola discovered integer overflows in PHP's pack() and unpack() functions. A malicious PHP script could exploit these to break out of safe mode and execute arbitrary code with the privileges of the PHP interpreter. (CAN-2004-1018) Note: The second part of CAN-2004-1018 (buffer overflow in the shmop_write() function) was already fixed in USN-66-1. Stefan Esser discovered two safe mode bypasses which allowed malicious PHP scripts to circumvent path restrictions. This was possible by either using virtual_popen() with a current directory containing shell metacharacters (CAN-2004-1063) or creating a specially crafted directory whose length exceeded the capacity of the realpath() function (CAN-2004-1064). Affected Software/OS: 'php4' package(s) on Ubuntu 4.10. Solution: Please install the updated package(s). CVSS Score: 10.0 CVSS Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C
