Summary
Red Hat Security Advisory: : Updated httpd packages fix Apache security vulnerabilities
Severity
Moderate
Notes
Topic: Updated httpd packages that fix two minor security issues in the Apache Web server are now available for Red Hat Linux 8.0 and 9.
Details: The Apache HTTP Server is a powerful, full-featured, efficient, and freely-available Web server. An issue in the handling of regular expressions from configuration files was discovered in releases of the Apache HTTP Server version 2.0 prior to 2.0.48. To exploit this issue an attacker would need to have the ability to write to Apache configuration files such as .htaccess or httpd.conf. A carefully-crafted configuration file can cause an exploitable buffer overflow and would allow the attacker to execute arbitrary code in the context of the server (in default configurations as the 'apache' user). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0542 to this issue. A bug in the CGI daemon-based "mod_cgid" module was discovered that can result in CGI script output being sent to the wrong client. This issue only affects Red Hat Linux 9, and only when the server is configured to use the "worker" MPM. The default configuration uses the "mod_cgi" module for CGI and is not affected by this issue. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0789 to this issue. Users of the Apache HTTP Server should upgrade to these erratum packages, which contain backported patches correcting these issues, and are applied to Apache version 2.0.40.

Multiple stack-based buffer overflows in (1) mod_alias and (2) mod_rewrite for Apache before 1.3.29 allow attackers to create configuration files to cause a denial of service (crash) or execute arbitrary code via a regular expression with more than 9 captures.

Threats
Impact Low

mod_cgid in Apache before 2.0.48, when using a threaded MPM, does not properly handle CGI redirect paths, which could cause Apache to send the output of a CGI program to the wrong client.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
