Description

Possible CRLF injection allowing HTTP response splitting attacks for sites which use mod_userdir. This issue was mitigated by changes made in 2.4.25 and 2.2.32 which prohibit CR or LF injection into the "Location" or other outbound header key or value.

Solution(s)

  • apache-httpd-upgrade-2_2_32
  • apache-httpd-upgrade-2_4_25
