Het ontwikkelteam van het Apache HTTP Server Project heeft onlangs een nieuwe versie uitgegeven van hun Apache HTTP-server. Deze webserver wordt op veel platformen gebruikt en heeft onder andere ondersteuning voor PHP. Het versienummer is aangekomen bij 2.0.55 en is voorzien van de volgende aankondiging:
This version of Apache is principally a security release. The following potential security flaws are addressed, the first three of which address several classes of HTTP Request and Response Splitting/Spoofing attacks:The Apache HTTP Project thanks all of the reporters of these issues and vulnerabilities for the responsible reporting and thorough analysis of these vulnerabilities.
- CAN-2005-2088
core: If a request contains both Transfer-Encoding and Content-Length headers, remove the Content-Length.
proxy_http: Correctly handle the Transfer-Encoding and Content-Length request headers. Discard the request Content-Length whenever chunked T-E is used, always passing one of either C-L or T-E chunked whenever the request includes a request body.- Unassigned
proxy_http: If a response contains both Transfer-Encoding and a Content-Length, remove the Content-Length and don't reuse the connection.- CAN-2005-2700
mod_ssl: Fix a security issue where "SSLVerifyClient" was not enforced in per-location context if "SSLVerifyClient optional" was configured in the vhost configuration.- CAN-2005-2491
pcre: Fix integer overflows in PCRE in quantifier parsing which could be triggered by a local user through use of a carefully crafted regex in an .htaccess file.- CAN-2005-2728
Fix cases where the byterange filter would buffer responses into memory.- CAN-2005-1268
mod_ssl: Fix off-by-one overflow whilst printing CRL information at "LogLevel debug" which could be triggered if configured to use a "malicious" CRL.
This release further addresses a number of cross-platform bugs, as well as specific issues on OS/X 10.4, Win32, AIX, and across all EBCDIC platforms, and adds compatibility with OpenSSL 0.9.8.
This release is compatible with modules compiled for 2.0.42 and later versions. We consider this release to be the best version of Apache available and encourage users of all prior versions to upgrade.
This release includes the Apache Portable Runtime library suite release version 0.9.7, bundled with the tar and zip distributions. These libraries; libapr, libaprutil, and on Win32, libapriconv must all be updated to ensure binary compatibility and address many known platform bugs.
