Garming Sam reported an out-of-bounds read in the ldb_wildcard_compare() function of ldb, a LDAP-like embedded database, resulting in denial of service.

For Debian 8 β€˜Jessie’, this problem has been fixed in version 2:1.1.20-0+deb8u2.

We recommend that you upgrade your ldb packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
