Synopsis

There are multiple format string vulnerabilities in the neon library used in cadaver, possibly leading to execution of arbitrary code when connected to a malicious server.

2.  Impact Information

Background

According to http://www.webdav.org/cadaver, cadaver is a command-line WebDAV client for Unix. It supports file upload, download, on-screen display, namespace operations (move/copy), collection creation and deletion, and locking operations.

Description

Cadaver code includes the neon library, which in versions 0.24.4 and previous is vulnerable to multiple format string attacks. The latest version of cadaver uses version 0.24.5 of the neon library, which makes it immune to this vulnerability.

Impact

When using cadaver to connect to an untrusted WebDAV server, this vulnerability can allow a malicious remote server to execute arbitrary code on the client with the rights of the user using cadaver.

3.  Resolution Information

Workaround

A workaround is not currently known for this issue. All users are advised to upgrade to the latest version of the affected package.

Resolution

cadaver users should upgrade to version 0.22.1 or later:

Code Listing 3.1: Resolution

# emerge sync
# emerge -pv ">=net-misc/cadaver-0.22.1"
# emerge ">=net-misc/cadaver-0.22.1"
