Description

This update of the Apache webserver fixes various security issues :

  • mod_proxy could run into an infinite loop when used as reverse proxy. (CVE-2009-1890)

  • mod_deflate continued to compress large files even after a network connection was closed, causing mod_deflate to consume large amounts of CPU. (CVE-2009-1891)

  • The ap_proxy_ftp_handler function in modules/proxy/proxy_ftp.c in the mod_proxy_ftp module allows remote FTP servers to cause a denial of service (NULL pointer dereference and child process crash) via a malformed reply to an EPSV command. (CVE-2009-3094)

  • access restriction bypass in mod_proxy_ftp module. (CVE-2009-3095)
