CVE-2022-2309 (GCVE-0-2022-2309)
Vulnerability from cvelistv5 – Published: 2022-07-05 09:00 – Updated: 2025-11-04 16:09
VLAI
Title
NULL Pointer Dereference in lxml/lxml
Summary
NULL Pointer Dereference allows attackers to cause a denial of service (or application crash). This only applies when lxml is used together with libxml2 2.9.10 through 2.9.14. libxml2 2.9.9 and earlier are not affected. It allows triggering crashes through forged input data, given a vulnerable code sequence in the application. The vulnerability is caused by the iterwalk function (also used by the canonicalize function). Such code shouldn't be in wide-spread use, given that parsing + iterwalk would usually be replaced with the more efficient iterparse function. However, an XML converter that serialises to C14N would also be vulnerable, for example, and there are legitimate use cases for this code sequence. If untrusted input is received (also remotely) and processed via iterwalk function, a crash can be triggered.

Title
Adobe Illustrator NULL Pointer Dereference Application denial-of-service
Summary
Adobe Illustrator versions 25.4.3 (and earlier) and 26.0.2 (and earlier) are affected by a Null pointer dereference vulnerability. An unauthenticated attacker could leverage this vulnerability to achieve an application denial-of-service in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Mitigation ID: MIT-56
Phase: Implementation
Description:
- For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Phase: Requirements
Description:
- Select a programming language that is not susceptible to these issues.
Mitigation
Phase: Implementation
Description:
- Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Phase: Architecture and Design
Description:
- Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Phase: Implementation
Description:
- Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
