The remote Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS / Pro Realtime 22.04 LTS / Pro Realtime 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8743-1 advisory.

    It was discovered that PHP incorrectly handled backslash escaping in the PostgreSQL extension. An attacker     could use this issue to perform SQL injection attacks. (CVE-2026-17543)

    It was discovered that PHP incorrectly handled certain inputs to the bccomp() function. An attacker could     use this issue to cause an out-of- bounds write, resulting in a denial of service or possibly execute     arbitrary code. This issue only affected Ubuntu 26.04 LTS. (CVE-2026-17544)

    It was discovered that PHP incorrectly handled circular symbolic links in phar archives. An attacker could     use this issue to cause unbounded recursion, resulting in a denial of service. (CVE-2026-7260)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-2041 advisory.

    Improper escaping of backslashes in attacker-provided parameters would allow for trivial SQL injection in     PHP versions from 8.2.* before 8.2.33, from 8.3.* before 8.3.33, from 8.4.* before 8.4.24, and from 8.5.*     before 8.5.9. (CVE-2026-17543)

    Attacker-provided inputs to bccomp() could lead to an out-of-bounds write with stack and heap corruption     in PHP versions from 8.4.* before 8.4.24 and from 8.5.* before 8.5.9. (CVE-2026-17544)

    Circular symbolic links in phar archives could lead to unbounded recursion, exhausting the C stack and     crashing the PHP process, in PHP versions from 8.2.* before 8.2.33, from 8.3.* before 8.3.33, from 8.4.*     before 8.4.24, and from 8.5.* before 8.5.9. (CVE-2026-7260)

    PHP is an HTML-embedded scripting language. PHP attempts to make it easy for developers to write     dynamically generated web pages. PHP also offers built-in database integration for several commercial and     non-commercial database management systems, so writing a database-enabled webpage with PHP is fairly     simple. The most common use of PHP coding is probably as a replacement for CGI scripts.

    Security Fix(es):

    * php: ext-pgsql: PHP: SQL injection via improper backslash escaping (CVE-2026-17543)
