Description

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.

• CWE-119Improper Restriction of Operations within the Bounds of a Memory BufferThe product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
