CVE-2018-12422 (CCN-144947)

Assigned:2018-06-15
Published:2018-06-15
Updated:2018-08-09
Summary:** DISPUTED ** addressbook/backends/ldap/e-book-backend-ldap.c in Evolution-Data-Server in GNOME Evolution through 3.29.2 might allow attackers to trigger a Buffer Overflow via a long query that is processed by the strcat function.
Note: the software maintainer disputes this because "the code had computed the required string length first, and then allocated a large-enough buffer on the heap."
