Package : php7.4
Version : 7.4.33-1+deb11u12
CVE ID : CVE-2026-7260 CVE-2026-17543
Debian Bug : 1143153
Security issues were found in PHP, a widely-used open source general
purpose scripting language, which could result in denial of service or
SQL injection.
CVE-2026-7260
Symbolic links in phar archives are followed without any depth limit
or cycle detection. A crafted tar-based phar archive containing
circular symbolic links could therefore cause unbounded recursion,
exhausting the C stack and crashing the PHP process.
CVE-2026-17543
Improper escaping of backslashes in attacker-provided parameters
allow for trivial SQL injection via E'…' backslash breakout.
For Debian 11 bullseye, these problems have been fixed in version
7.4.33-1+deb11u12.
We recommend that you upgrade your php7.4 packages.
