CVE-2021-39242 4 Debian, Fedoraproject, Haproxy and 1 more 4 Debian Linux, Fedora, Haproxy and 1 more 2024-11-21 7.5 High
An issue was discovered in HAProxy 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. It can lead to a situation with an attacker-controlled HTTP Host header, because a mismatch between Host and authority is mishandled.
CVE-2021-39241 4 Debian, Fedoraproject, Haproxy and 1 more 4 Debian Linux, Fedora, Haproxy and 1 more 2024-11-21 5.3 Medium
An issue was discovered in HAProxy 2.0 before 2.0.24, 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. An HTTP method name may contain a space followed by the name of a protected resource. It is possible that a server would interpret this as a request for that protected resource, such as in the "GET /admin? HTTP/1.1 /static/images HTTP/1.1" example.
CVE-2021-39240 4 Debian, Fedoraproject, Haproxy and 1 more 4 Debian Linux, Fedora, Haproxy and 1 more 2024-11-21 7.5 High
An issue was discovered in HAProxy 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. It does not ensure that the scheme and path portions of a URI have the expected characters. For example, the authority field (as observed on a target HTTP/2 server) might differ from what the routing rules were intended to achieve.
CVE-2021-39191 4 Debian, Fedoraproject, Openidc and 1 more 4 Debian Linux, Fedora, Mod Auth Openidc and 1 more 2024-11-21 4.7 Medium
mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. In versions prior to 2.4.9.4, the 3rd-party init SSO functionality of mod_auth_openidc was reported to be vulnerable to an open redirect attack by supplying a crafted URL in the `target_link_uri` parameter. A patch in version 2.4.9.4 made it so that the `OIDCRedirectURLsAllowed` setting must be applied to the `target_link_uri` parameter. There are no known workarounds aside from upgrading to a patched version.
CVE-2021-39156 2 Istio, Redhat 2 Istio, Service Mesh 2024-11-21 8.1 High
Istio is an open source platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. Istio 1.11.0, 1.10.3 and below, and 1.9.7 and below contain a remotely exploitable vulnerability where an HTTP request with `#fragment` in the path may bypass Istio’s URI path based authorization policies. Patches are available in Istio 1.11.1, Istio 1.10.4 and Istio 1.9.8. As a work around a Lua filter may be written to normalize the path.
CVE-2021-39155 2 Istio, Redhat 2 Istio, Service Mesh 2024-11-21 8.3 High
Istio is an open source platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. According to [RFC 4343](https://datatracker.ietf.org/doc/html/rfc4343), Istio authorization policy should compare the hostname in the HTTP Host header in a case insensitive way, but currently the comparison is case sensitive. The proxy will route the request hostname in a case-insensitive way which means the authorization policy could be bypassed. As an example, the user may have an authorization policy that rejects request with hostname "httpbin.foo" for some source IPs, but the attacker can bypass this by sending the request with hostname "Httpbin.Foo". Patches are available in Istio 1.11.1, Istio 1.10.4 and Istio 1.9.8. As a work around a Lua filter may be written to normalize Host header before the authorization check. This is similar to the Path normalization presented in the [Security Best Practices](https://istio.io/latest/docs/ops/best-practices/security/#case-normalization) guide.
CVE-2021-39013 2 Ibm, Redhat 2 Cloud Pak For Security, Openshift 2024-11-21 6.5 Medium

CVE-2021-38593 3 Fedoraproject, Qt, Redhat 3 Fedora, Qt, Enterprise Linux 2024-11-21 7.5 High
Qt 5.x before 5.15.6 and 6.x through 6.1.2 has an out-of-bounds write in QOutlineMapper::convertPath (called from QRasterPaintEngine::fill and QPaintEngineEx::stroke).
CVE-2021-38509 3 Debian, Mozilla, Redhat 6 Debian Linux, Firefox, Firefox Esr and 3 more 2024-11-21 4.3 Medium
Due to an unusual sequence of attacker-controlled events, a Javascript alert() dialog with arbitrary (although unstyled) contents could be displayed over top an uncontrolled webpage of the attacker's choosing. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.
CVE-2021-38508 3 Debian, Mozilla, Redhat 6 Debian Linux, Firefox, Firefox Esr and 3 more 2024-11-21 4.3 Medium
By displaying a form validity message in the correct location at the same time as a permission prompt (such as for geolocation), the validity message could have obscured the prompt, resulting in the user potentially being tricked into granting the permission. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.
CVE-2021-38507 3 Debian, Mozilla, Redhat 6 Debian Linux, Firefox, Firefox Esr and 3 more 2024-11-21 6.5 Medium
The Opportunistic Encryption feature of HTTP2 (RFC 8164) allows a connection to be transparently upgraded to TLS while retaining the visual properties of an HTTP connection, including being same-origin with unencrypted connections on port 80. However, if a second encrypted port on the same IP address (e.g. port 8443) did not opt-in to opportunistic encryption; a network attacker could forward a connection from the browser to port 443 to port 8443, causing the browser to treat the content of port 8443 as same-origin with HTTP. This was resolved by disabling the Opportunistic Encryption feature, which had low usage. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.
CVE-2021-38506 3 Debian, Mozilla, Redhat 6 Debian Linux, Firefox, Firefox Esr and 3 more 2024-11-21 4.3 Medium
Through a series of navigations, Firefox could have entered fullscreen mode without notification or warning to the user. This could lead to spoofing attacks on the browser UI including phishing. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.
CVE-2021-38504 3 Debian, Mozilla, Redhat 6 Debian Linux, Firefox, Firefox Esr and 3 more 2024-11-21 8.8 High
When interacting with an HTML input element's file picker dialog with webkitdirectory set, a use-after-free could have resulted, leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.
CVE-2021-38503 3 Debian, Mozilla, Redhat 6 Debian Linux, Firefox, Firefox Esr and 3 more 2024-11-21 10.0 Critical
The iframe sandbox rules were not correctly applied to XSLT stylesheets, allowing an iframe to bypass restrictions such as executing scripts or navigating the top-level frame. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.
CVE-2021-38502 3 Debian, Mozilla, Redhat 4 Debian Linux, Thunderbird, Enterprise Linux and 1 more 2024-11-21 5.9 Medium
Thunderbird ignored the configuration to require STARTTLS security for an SMTP connection. A MITM could perform a downgrade attack to intercept transmitted messages, or could take control of the authenticated session to execute SMTP commands chosen by the MITM. If an unprotected authentication method was configured, the MITM could obtain the authentication credentials, too. This vulnerability affects Thunderbird < 91.2.
