Lifecycle Timeline
4Description
A vulnerability has been identified in the libarchive library. This flaw involves an integer overflow that can be triggered when processing a Web Archive (WARC) file that claims to have more than INT64_MAX - 4 content bytes. An attacker could craft a malicious WARC archive to induce this overflow, potentially leading to unpredictable program behavior, memory corruption, or a denial-of-service condition within applications that process such archives using libarchive. This bug affects libarchive versions prior to 3.8.0.
Analysis
A vulnerability has been identified in the libarchive library. This flaw involves an integer overflow that can be triggered when processing a Web Archive (WARC) file that claims to have more than INT64_MAX - 4 content bytes. An attacker could craft a malicious WARC archive to induce this overflow, potentially leading to unpredictable program behavior, memory corruption, or a denial-of-service condition within applications that process such archives using libarchive. This bug affects libarchive versions prior to 3.8.0.
Technical Context
An integer overflow occurs when an arithmetic operation produces a value that exceeds the maximum (or minimum) size of the integer type used to store it. This vulnerability is classified as Integer Overflow or Wraparound (CWE-190).
Affected Products
Affected products: Libarchive Libarchive, Redhat Openshift Container Platform 4.0, Redhat Enterprise Linux 6.0
Remediation
A vendor patch is available — apply it immediately. Use safe integer arithmetic libraries. Check for overflow conditions before operations. Use appropriately sized integer types.
