The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:4123 advisory.

  - 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-2021-38503)

  - 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-2021-38504)

  - 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-2021-38506)

  - 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-2021-38507)

  - 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-2021-38508)

  - 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-2021-38509)

The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2021:4511 advisory.

  - curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl. This rarely used     option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for     sending `NEW_ENV` variables, libcurlcould be made to pass on uninitialized data from a stack based buffer     to theserver. Therefore potentially revealing sensitive internal information to theserver using a clear-     text network protocol.This could happen because curl did not call and use sscanf() correctly whenparsing     the string provided by the application. (CVE-2021-22925)

The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2021:2034 advisory.

  - Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and     message broker. An integer overflow bug in Redis version 6.0 or newer could be exploited using the     `STRALGO LCS` command to corrupt the heap and potentially result with remote code execution. The problem     is fixed in version 6.2.3 and 6.0.13. An additional workaround to mitigate the problem without patching     the redis-server executable is to use ACL configuration to prevent clients from using the `STRALGO LCS`     command. (CVE-2021-29477)

  - runc before 1.0.0-rc95 allows a Container Filesystem Breakout via Directory Traversal. To exploit the     vulnerability, an attacker must be able to create multiple containers with a fairly specific mount     configuration. The problem occurs via a symlink-exchange attack that relies on a race condition.

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:2264 advisory.

  - OpenPGP secret keys that were imported using Thunderbird version 78.8.1 up to version 78.10.1 were stored     unencrypted on the user's local disk. The master password protection was inactive for those keys. Version     78.10.2 will restore the protection mechanism for newly imported keys, and will automatically protect keys     that had been imported using affected Thunderbird versions. This vulnerability affects Thunderbird <     78.10.2. (CVE-2021-29956)

  - If a MIME encoded email contains an OpenPGP inline signed or encrypted message part, but also contains an     additional unprotected part, Thunderbird did not indicate that only parts of the message are protected.
    This vulnerability affects Thunderbird < 78.10.2. (CVE-2021-29957)

  - Mozilla developers reported memory safety bugs present in Firefox 88 and Firefox ESR 78.11. Some of these     bugs showed evidence of memory corruption and we presume that with enough effort some of these could have     been exploited to run arbitrary code. This vulnerability affects Thunderbird < 78.11, Firefox < 89, and     Firefox ESR < 78.11. (CVE-2021-29967)

  - A heap buffer overflow vulnerability in msadpcm_decode_block of libsndfile 1.0.30 allows attackers to     execute arbitrary code via a crafted WAV file. (CVE-2021-3246)
