Packages

Details

It was discovered that Smarty, that is integrated in the PostfixAdmin
code, was not properly sanitizing user input when generating templates. An
attacker could, through PHP injection, possibly use this issue to execute
arbitrary code. (CVE-2022-29221)

It was discovered that Moment.js, that is integrated in the PostfixAdmin
code, was using an inefficient parsing algorithm when processing date
strings in the RFC 2822 standard. An attacker could possibly use this
issue to cause a denial of service. This issue only affected Ubuntu 22.04
LTS. (CVE-2022-31129)

It was discovered that Smarty, that is integrated in the PostfixAdmin
code, was not properly escaping JavaScript code. An attacker could
possibly use this issue to conduct cross-site scripting attacks (XSS).
(CVE-2023-28447)
