| Package | Affected versions | Patched versions |
|---|---|---|
| python-ldap | < 3.4.0 | 3.4.0 |
| python-ldap | < 3.4.0 | 3.4.0 |
python-ldap before 3.4.0 is vulnerable to a denial of service when ldap.schema is used for untrusted schema definitions, because of a regular expression denial of service (ReDoS) flaw in the LDAP schema parser. By sending crafted regex input, a remote authenticated attacker could exploit this vulnerability to cause a denial of service condition.
