AIDE is an advanced intrusion detection environment. From versions 0.13 to 0.19.1, there is a null pointer dereference vulnerability in AIDE. An attacker can crash the program during report printing or database listing after setting extended file attributes with an empty attribute value or with a key containing a comma. A local user might exploit this to cause a local denial of service. This issue has been patched in version 0.19.2. A workaround involves removing xattrs group from rules matching files on affected file systems.

A flaw was discovered an improper output neutralization vulnerability in AIDE, an advanced intrusion detection system. An attacker can craft a malicious filename by including terminal escape sequences to hide the addition or removal of the file from the report and/or tamper with the log output. A local user might exploit this to bypass the AIDE detection of malicious files. Additionally the output of extended attribute key names and symbolic links targets are also not properly neutralized.

A heap-based buffer overflow vulnerability in base64 functions of AIDE, an advanced intrusion detection system. An attacker could crash the program and possibly execute arbitrary code through large (<16k) extended file attributes or ACL. A local user might exploit this flaw for root privilege escalation.
