Bug ID: 2541
Summary: segfault on invalid -f flag
Product: Exim
Version: 4.93
Hardware: x86
OS: Linux
Status: NEW
Severity: bug
Priority: medium
Component: General execution
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
The taint functionality added to the CLI "-f" flag in version 4.93 will end up
calling
sender_address = string_copy_taint(sender_address, TRUE);
when sender_address is a null pointer. This segfaults when
string_copy_taint_trc() tries to determine the length of the string.
To reproduce the crash run:
exim -f @ -bV
