This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.
https://github.com/python-pillow/Pillow/pull/7244

Affected versions of the pillow package are vulnerable to Integer Overflow due to unchecked accumulation of glyph advance values while tracking the current rendering position during font processing. When a font supplies an excessively large advance for each glyph, the running position counter wraps around because the arithmetic is performed in a fixed-width integer type that cannot represent the resulting magnitude. A remote attacker who can supply a crafted font file to a target that uses Pillow's font rendering can trigger the overflow, leading to incorrect memory calculations and potential memory corruption.

libImaging/PcxDecode.c in Pillow before 6.2.2 has a PCX P mode buffer overflow.

Django-allauth 0.33 includes a security fix: Leakage of password reset token on a third-party website through the Referer header.

Django-allauth 0.47.0 adds a new setting 'SOCIALACCOUNT_LOGIN_ON_GET' that controls whether or not the endpoints for initiating a social login (for example, "/accounts/google/login/") require a POST request to initiate the handshake. As requiring a POST is more secure, the default of this new setting is 'False'. This is useful to prevent redirect attacks.

On django-allauth before 0.34.0 the "Set Password" view did not properly check whether or not the user already had a usable password set. This allowed an attacker to set the password without providing the current password, but only in case the attacker already gained control over the victim's session.

Django-allauth 0.54.0 includes a security fix: Even when account enumeration prevention was turned on, it was possible for an attacker to infer whether or not a given account exists based upon the response time of an authentication attempt.

Affected versions of the django-allauth package are vulnerable to Open Redirect due to improper validation of the SAML RelayState parameter when IdP-initiated SSO is enabled. In the SAML login flow, django-allauth accepts any URL supplied in RelayState and uses it as the post-authentication redirect target, allowing untrusted external destinations to be processed without restriction when IdP-initiated SSO is turned on, which is disabled by default.

Affected versions of allauth are vulnerable to account enumeration through timing attacks (CWE-203). This vulnerability allows attackers to determine the existence of user accounts by measuring response times during email/password authentication attempts. The issue resides in the AuthenticationBackend._authenticate_by_email method, which did not mitigate timing discrepancies. Exploitation can be performed remotely with high feasibility. Users should update to the latest version of allauth to apply the implemented timing attack mitigations.

Affected versions of Django-allauth are vulnerable to CSRF and replay attacks in the SAML login flow. RelayStatewas used to keep track of whether or not the login flow was IdP or SP initiated. As RelayState is a separate field, not part of the SAMLResponse payload, it was not signed, causing the vulnerability.

Django-allauth before 0.28.0 contained a vulnerability allowing an attacker to alter the provider specific settings for 'SCOPE' and/or 'AUTH_PARAMS' (part of the  larger 'SOCIALACCOUNT_PROVIDERS' setting). The changes would persist across subsequent requests for all users, provided these settings were explicitly set within your project. These settings translate directly into request parameters, giving the attacker undesirable control over the OAuth(2) handshake. You are not affected if you did not explicitly configure these settings.
https://github.com/pennersr/django-allauth/commit/492ba9739b323cb66ef4020259c1db2d49cb6526

Affected versions of the django-allauth package are vulnerable to Authorization Bypass due to the use of a mutable identifier (preferred_username) from third-party providers for authorization decisions. The authentication logic in django-allauth’s social account handling uses the preferred_username field from Okta and NetIQ OpenID Connect identity providers as the canonical user identifier, which may be changed by an attacker and is not stable enough to base authorization on; the code fails to validate that the identifier is immutable.

Django-allauth 0.41.0 conforms to the general Django 3.0.1, 2.2.9, and 1.11.27 security release. See CVE-2019-19844 and <https://www.djangoproject.com/weblog/2019/dec/18/security-releases/>.

Affected versions of the django-allauth package are vulnerable to Insufficient Session Expiration due to access and refresh tokens remaining valid after the associated user account is deactivated. In django-allauth’s IdP OpenID Connect implementation, allauth/idp/oidc/internal/oauthlib/request_validator.py does not check instance.user.is_active in validate_bearer_token() and validate_refresh_token(), and allauth/idp/oidc/internal/oauthlib/device_codes.py previously returned token state without revalidating the user’s active status.

In Django-allauth, a vulnerability allows attackers to inject arbitrary JavaScript into the login page when configuring the Facebook provider to use the `js_sdk` method, potentially compromising user sessions or stealing sensitive information.

Django-allauth 0.30.0 includes a fix for a Denial of Service vulnerability.
https://github.com/pennersr/django-allauth/commit/8dc2f2d5cc3ce0e5e1b999129ceaa57ed4e75390

Gevent 1.2a1 no longer prints the entire WSGI environment by default for errors logged by :class:'~gevent.pywsgi.WSGIHandler'.
https://github.com/gevent/gevent/pull/781

Affected versions of gevent were potentially vulnerable to HTTP request smuggling. The issue existed in the pywsgi Input._send_100_continue handling.

Affected versions of gevent are potentially vulnerable to a Race Condition leading to Unauthorized Access — CWE-362.

An issue in Gevent before version 23.9.0 allows a remote attacker to escalate privileges via a crafted script to the WSGIServer component.
