High

Base vector

AV:N/AC:M/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions: Enhanced CTorrent versions 3.3.2 and earlier CTorrent version 1.3.4

Description: The issue is related to a stack-based buffer overflow in the btFiles::BuildFromMI function, which can be triggered by a Torrent file containing a long path. This can cause a denial of service (crash) and potentially allow remote attackers to execute arbitrary code.

Recommendations: For Enhanced CTorrent versions 3.3.2 and earlier, consider updating to a newer version that addresses this issue. For CTorrent version 1.3.4, consider updating to a newer version that addresses this issue. As a temporary workaround, consider restricting the handling of Torrent files with long paths to minimize the risk of exploitation.
