jailer 'updatejail' Insecure Temporary File Creation Vulnerability
BalaBit 'jailer' creates temporary files in an insecure manner. An attacker with local access could perform symbolic-link attacks, overwriting arbitrary files in the context of the affected application. Successfully mounting a symlink attack may allow the attacker to delete or corrupt sensitive files, which may result in a denial of service. Other attacks may also be possible. This issue affects 'jailer' 0.4; other versions may also be affected. |
