<br><dt>More information:</dt>
<dd>Several remote vulnerabilities have been discovered in PHP, a <br>
server-side, HTML-embedded scripting language, which may lead to the <br>
execution of arbitrary code. The Common Vulnerabilities and Exposures <br>
project identifies the following problems: <br>
<br>
CVE-2007-1286 <br>
Stefan Esser discovered an overflow in the object reference handling <br>
code of the unserialize() function, which allows the execution of <br>
arbitrary code if malformed input is passed from an application. <br>
<br>
CVE-2007-1375 <br>
Stefan Esser discovered that an integer overflow in the substr_compare() <br>
function allows information disclosure of heap memory. <br>
<br>
CVE-2007-1376 <br>
Stefan Esser discovered that insufficient validation of shared memory <br>
functions allows the disclosure of heap memory. <br>
<br>
CVE-2007-1380 <br>
Stefan Esser discovered that the session handler performs <br>
insufficient validation of variable name length values, which allows <br>
information disclosure through a heap information leak. <br>
<br>
CVE-2007-1453 <br>
Stefan Esser discovered that the filtering framework performs insufficient <br>
input validation, which allows the execution of arbitrary code through a <br>
buffer underflow. <br>
<br>
CVE-2007-1454 <br>
Stefan Esser discovered that the filtering framework can be bypassed <br>
with a special whitespace character. <br>
<br>
CVE-2007-1521 <br>
Stefan Esser discovered a double free vulnerability in the <br>
session_regenerate_id() function, which allows the execution of <br>
arbitrary code. <br>
<br>
CVE-2007-1583 <br>
Stefan Esser discovered that a programming error in the mb_parse_str() <br>
function allows the activation of "register_globals". <br>
<br>
CVE-2007-1700 <br>
Stefan Esser discovered that the session extension incorrectly maintains <br>
the reference count of session variables, which allows the execution of <br>
arbitrary code. <br>
<br>
CVE-2007-1718 <br>
Stefan Esser discovered that the mail() function performs <br>
insufficient validation of folded mail headers, which allows mail <br>
header injection. <br>
<br>
CVE-2007-1777 <br>
Stefan Esser discovered that the extension to handle ZIP archives <br>
performs insufficient length checks, which allows the execution of <br>
arbitrary code. <br>
<br>
CVE-2007-1824 <br>
Stefan Esser discovered an off-by-one in the filtering framework, which <br>
allows the execution of arbitrary code. <br>
<br>
CVE-2007-1887 <br>
Stefan Esser discovered that a buffer overflow in the sqlite extension <br>
allows the execution of arbitrary code. <br>
<br>
CVE-2007-1889 <br>
Stefan Esser discovered that the PHP memory manager performs an <br>
incorrect type cast, which allows the execution of arbitrary code <br>
through buffer overflows. <br>
<br>
CVE-2007-1900 <br>
Stefan Esser discovered that incorrect validation in the email filter <br>
extension allowed the injection of mail headers. <br>
<br>
CVE-2007-2509 <br>
It was discovered that missing input sanitising inside the ftp <br>
extension permits an attacker to execute arbitrary FTP commands. <br>
This requires the attacker to already have access to the FTP <br>
server. <br>
<br>
CVE-2007-2510 <br>
It was discovered that a buffer overflow in the SOAP extension permits <br>
the execution of arbitrary code. <br>
<br>
CVE-2007-2511 <br>
A buffer overflow was discovered in the user_filter_factory_create. <br>
</dd>
<br><dt>For the testing distribution (lenny) this is fixed in version 5.2.0-10+lenny1</dt>
<dt>For the unstable distribution (sid) this is fixed in version 5.2.2-1</dt>
<br><dt>This upgrade is recommended if you use php5.<dt>
<br><dt>If you have the secure testing lines in your sources.list, you can update by running this command as root:</dt>
<dd>apt-get update && apt-get upgrade</dd>
<br>
<br>
<dt>To use the Debian testing security archive, add the following lines to your /etc/apt/sources.list:<dt>
