IBM Informix Dynamic Server DBLANG directory traversal
|ibm-ids-dblang-directory-traversal (38297)||High Risk|
IBM Informix Dynamic Server could allow a local attacker to traverse directories and gain elevated privileges on the system, caused by improper validation of the DBLANG environment variable. An attacker could exploit this vulnerability to gain root privileges on the system by using an unspecified setuid binary to set the DBLANG variable to a specially-crafted value containing "dot dot" (../) sequences.
Upgrade to the latest version of IBM Informix Dynamic Server (10.00.xC7W1 or later), available from the IBM Support & downloads Web site. See References.
