stride vulnerability

About this tag
The stride vulnerability tag covers security flaws related to improper handling of stride values in image processing libraries, particularly libpng. A notable example is CVE-2026-22801, an integer truncation bug in libpng's simplified write APIs that can cause a heap buffer over-read and denial-of-service when applications pass malformed stride values. This vulnerability affects libpng versions 1.6.26 through 1.6.53 and was fixed in version 1.6.54. Discussions on WindowsForum.com focus on the technical details of such stride-related bugs, their impact on system stability and security, and the importance of applying vendor updates to mitigate risks.
