Summary
A symlink traversal vulnerability was found in the getfattr and setfattr utilities of the attr package before version 2.6.0. A local attacker can replace a pathname component with a symbolic link during directory hierarchy traversal, leading to privilege escalation.
Risk Assessment
If a privileged process invokes getfattr or setfattr on an attacker-controlled path, the attacker can redirect operations to arbitrary files, resulting in local privilege escalation and potential full system compromise.
Recommendation
Immediately upgrade the attr package to version 2.6.0 or later, which fixes this vulnerability. Until then, avoid using getfattr and setfattr on paths from untrusted users.

Improper neutralization of CRLF sequences in IXON VPN Client before version 1.4.7 allows an attacker to execute commands as root or SYSTEM. Configuration values accepted by the local service are written to a file later consumed by a privileged subprocess, without line-ending sequences being neutralized, which allows additional directives to be introduced into that file. The configuration interface accepts changes without authenticating or verifying the origin of the requester. The injected configuration persists on disk across restarts of the client and the operating system, and the VPN connection continues to function normally, so there is no behavioral change visible to the user.

Original NVD description (English source)
attr before version 2.6.0 contains a symlink traversal vulnerability in the getfattr and setfattr utilities that allows local attackers to escalate privileges by replacing a pathname component with a symbolic link during directory hierarchy traversal. Attackers who control a pathname component can redirect getfattr and setfattr operations to arbitrary files by substituting a symlink, leading to local privilege escalation when getfattr or setfattr is invoked by a privileged process over an attacker-controlled path.
