Original advisory details:

 Elias Myllymaki discovered that Django incorrectly handled certain inputs
 with a large number of brackets. A remote attacker could possibly use this
 issue to cause Django to consume resources or stop responding, resulting in
 a denial of service. (CVE-2024-38875)

 It was discovered that Django incorrectly handled authenticating users with
 unusable passwords. A remote attacker could possibly use this issue to
 perform a timing attack and enumerate users. (CVE-2024-39329)

 Josh Schneier discovered that Django incorrectly handled file path
 validation when the storage class is being derived. A remote attacker could
 possibly use this issue to save files into arbitrary directories.
 (CVE-2024-39330)

 It was discovered that Django incorrectly handled certain long strings that
 included a specific set of characters. A remote attacker could possibly use
 this issue to cause Django to consume resources or stop responding,
 resulting in a denial of service. (CVE-2024-39614)");
