CVE-2025-25724

A flaw was found in the libarchive package. Affected versions of libarchive do not check a strftime return value, which can lead to a denial of service or unspecified other impacts via a crafted TAR archive that is read with a verbose value of 2. For example, the 100-byte buffer may not be sufficient for a custom locale.

Red Hat employs static and dynamic security testing and numerous program hardening technologies as part of our Secure Development Lifecycle. These tests and means of hardening our software prevent or reduce the impact of flaws and increase the complexity of attacks.

Return values from critical operations are consistently evaluated through enforced development standards and automated static analysis, reducing the likelihood of logic flaws or silent failures reaching production. Error-handling routines are integrated into application behavior to ensure that failures are properly logged, traced, and contained, maintaining system stability under fault conditions. Additionally, the platform is designed to respond to errors predictably, preventing uncontrolled behavior and ensuring that processes fail in a known, recoverable state.
