CWE-416
AllowedUse After Free
Abstraction: Variant · Status: Stable
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
10993 vulnerabilities reference this CWE, most recent first.

GHSA-24X4-6QMH-88QG
Vulnerability from github – Published: 2022-02-09 23:57 – Updated: 2024-11-07 22:28Impact
A malicious user can cause a use after free behavior when decoding PNG images:
if (/* ... error conditions ... */) {
png::CommonFreeDecode(&decode);
OP_REQUIRES(context, false,
errors::InvalidArgument("PNG size too large for int: ",
decode.width, " by ", decode.height));
}
After png::CommonFreeDecode(&decode) gets called, the values of decode.width and decode.height are in an unspecified state.
Patches
We have patched the issue in GitHub commit e746adbfcfee15e9cfdb391ff746c765b99bdf9b.
The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.
For more information
Please consult our security guide for more information regarding the security model and how to contact us with issues and questions.

Mitigation
Strategy: Language Selection
Choose a language that provides automatic memory management.
Mitigation
Strategy: Attack Surface Reduction
When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
