[php-maint] Bug#441972: php5: 2 minor security problems: CVE-2007-4784 and CVE-2007-4783

Package: php5
Severity: normal
Tags: security

Hi

Two new CVEs[0,1] have been allocated against php5. Please investigate, if
the Debian versions are affected and if so monitor the CVE and see, if
there can be a solution :)
Please always mention the CVE id in the changelog, if a fix is uploaded.


CVE-2007-4784:
The setlocale function in PHP before 5.2.4 allows context-dependent
attackers to cause a denial of service (application crash) via a long
string in the locale parameter. NOTE: this might not be a vulnerability
in most web server environments that support multiple threads, unless
this issue can be demonstrated for code execution.



CVE-2007-4783:
The iconv_substr function in PHP 5.2.4 and earlier allows
context-dependent attackers to cause (1) a denial of service
(application crash) via a long string in the charset parameter, probably
also requiring a long string in the str parameter; or (2) a denial of
service (temporary application hang) via a long string in the str
parameter. NOTE: this might not be a vulnerability in most web server
environments that support multiple threads, unless these issues can be
demonstrated for code execution.


Thanks for your efforts.

Cheers
Steffen
