More information:
Several remote vulnerabilities have been discovered in PHP, a 
server-side, HTML-embedded scripting language, which may lead to the 
execution of arbitrary code. The Common Vulnerabilities and Exposures 
project identifies the following problems: 
 
CVE-2007-1286 
Stefan Esser discovered an overflow in the object reference handling 
code of the unserialize() function, which allows the execution of 
arbitrary code if malformed input is passed from an application. 
 
CVE-2007-1375 
Stefan Esser discovered that an integer overflow in the substr_compare() 
function allows information disclosure of heap memory. 
 
CVE-2007-1376 
Stefan Esser discovered that insufficient validation of shared memory 
functions allows the disclosure of heap memory. 
 
CVE-2007-1380 
Stefan Esser discovered that the session handler performs 
insufficient validation of variable name length values, which allows 
information disclosure through a heap information leak. 
 
CVE-2007-1453 
Stefan Esser discovered that the filtering framework performs insufficient 
input validation, which allows the execution of arbitrary code through a 
buffer underflow. 
 
CVE-2007-1454 
Stefan Esser discovered that the filtering framework can be bypassed  
with a special whitespace character. 
 
CVE-2007-1521 
Stefan Esser discovered a double free vulnerability in the 
session_regenerate_id() function, which allows the execution of 
arbitrary code.  
 
CVE-2007-1583 
Stefan Esser discovered that a programming error in the mb_parse_str() 
function allows the activation of "register_globals". 
 
CVE-2007-1700 
Stefan Esser discovered that the session extension incorrectly maintains 
the reference count of session variables, which allows the execution of 
arbitrary code. 
 
CVE-2007-1718 
Stefan Esser discovered that the mail() function performs 
insufficient validation of folded mail headers, which allows mail 
header injection. 
 
CVE-2007-1777 
Stefan Esser discovered that the extension to handle ZIP archives 
performs insufficient length checks, which allows the execution of 
arbitrary code. 
 
CVE-2007-1824 
Stefan Esser discovered an off-by-one in the filtering framework, which 
allows the execution of arbitrary code. 
 
CVE-2007-1887 
Stefan Esser discovered that a buffer overflow in the sqlite extension 
allows the execution of arbitrary code. 
 
CVE-2007-1889 
Stefan Esser discovered that the PHP memory manager performs an 
incorrect type cast, which allows the execution of arbitrary code 
through buffer overflows.  
 
CVE-2007-1900 
Stefan Esser discovered that incorrect validation in the email filter 
extension allowed the injection of mail headers. 
 
CVE-2007-2509 
It was discovered that missing input sanitising inside the ftp 
extension permits an attacker to execute arbitrary FTP commands. 
This requires the attacker to already have access to the FTP 
server. 
 
CVE-2007-2510 
It was discovered that a buffer overflow in the SOAP extension permits 
the execution of arbitrary code. 
 
CVE-2007-2511 
A buffer overflow was discovered in the user_filter_factory_create. 

For the testing distribution (lenny) this is fixed in version 5.2.0-10+lenny1
For the unstable distribution (sid) this is fixed in version 5.2.2-1

This upgrade is recommended if you use php5.

If you have the secure testing lines in your sources.list, you can update by running this command as root:
