Aria2 · Aria2 · CVE-2009-3617
**Name of the Vulnerable Software and Affected Versions**
aria2 versions prior to 1.6.2
**Description**
The issue allows remote attackers to execute arbitrary code or cause a denial of service, specifically an application crash, via format string specifiers in a download URI when logging is enabled. This is related to a format string vulnerability in the AbstractCommand::onAbort function.
**Recommendations**
For versions prior to 1.6.2, update to version 1.6.2 or later to resolve the issue. As a temporary workaround, consider disabling logging to minimize the risk of exploitation. Restrict access to download URIs that may contain format string specifiers to prevent potential attacks.
