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