    Multiple vulnerabilities were found in sqlparse, a non-validating SQL     parser for Python, which can lead to Denial of Service.

    CVE-2021-32839

        Erik Krogh Kristensen discovered that the StripComments filter         contains a regular expression that is vulnerable to ReDOS (Regular         Expression Denial of Service).  The regular expression may cause         exponential backtracking on strings containing many repetitions of         '\r\n' in SQL comments.

    CVE-2023-30608

        Erik Krogh Kristensen discovered that the Parser contains a regular         expression that is vulnerable to ReDOS (Regular Expression Denial of         Service).

    CVE-2024-4340

        Uriya Yavniely discovered that passing a heavily nested list to         sqlparse.parse() may raise a RecursionError exception.  A generic         SQLParseError is now raised instead.

    For Debian 11 bullseye, these problems have been fixed in version     0.4.1-1+deb11u1.

    We recommend that you upgrade your sqlparse packages.
