Bug ID: 2521
Summary: Maybe insufficient buffer in host_name_lookup()
Product: Exim
Version: 4.93
Hardware: x86-64
OS: Linux
Status: NEW
Severity: bug
Priority: medium
Component: Unfiled
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
I strongly doubt that the line 1693 of host.c in exim 4.93
int count = 0;
should be
int count = 1;
because store_get allocates (count * sizeof(uschar *)) buffer, but we need one
more redundant area to store the end of alias list by
*aptr = NULL;
in line 1744.
