- Update from version 8.2 with patch 1 to 8.2 with patches 1 to 10
- Update of rootfile not required
- Changelog
Patch 10
Fix the case where text to be completed from the line buffer (quoted) is
compared to the common prefix of the possible matches (unquoted) and the
quoting makes the former appear to be longer than the latter. Readline
assumes the match doesn't add any characters to the word and doesn't display
multiple matches.
Patch 9
Fix issue where the directory name portion of the word to be completed (the
part that is passed to opendir()) requires both tilde expansion and dequoting.
Readline only performed tilde expansion in this case, so filename completion
would fail.
Patch 8
Add missing prototypes for several function declarations.
Patch 7
If readline is called with no prompt, it should display a newline if return
is typed on an empty line. It should still suppress the final newline if
return is typed on the last (empty) line of a multi-line command.
Patch 6
This is a variant of the same issue as the one fixed by patch 5. In this
case, the signal arrives and is pending before readline calls rl_getc().
When this happens, the pending signal will be handled by the loop, but may
alter or destroy some state that the callback uses. Readline needs to treat
this case the same way it would if a signal interrupts pselect/select, so
compound operations like searches and reading numeric arguments get cleaned
up properly.
Patch 5
If an application is using readline in callback mode, and a signal arrives
after readline checks for it in rl_callback_read_char() but before it
restores the application's signal handlers, it won't get processed until the
next time the application calls rl_callback_read_char(). Readline needs to
check for and resend any pending signals after restoring the application's
signal handlers.
Patch 4
There are systems that supply one of select or pselect, but not both.
Patch 3
The custom color prefix that readline uses to color possible completions
must have a leading `.'.
Patch 2
It's possible for readline to try to zero out a line that's not null-
terminated, leading to a memory fault.

These include (amongst others) fixes for:
GLIBC-SA-2024-0001:
===================
syslog: Heap buffer overflow in __vsyslog_internal (CVE-2023-6246)
__vsyslog_internal did not handle a case where printing a SYSLOG_HEADER
containing a long program name failed to update the required buffer
size, leading to the allocation and overflow of a too-small buffer on
the heap.
GLIBC-SA-2024-0002:
===================
syslog: Heap buffer overflow in __vsyslog_internal (CVE-2023-6779)
__vsyslog_internal used the return value of snprintf/vsnprintf to
calculate buffer sizes for memory allocation. If these functions (for
any reason) failed and returned -1, the resulting buffer would be too
small to hold output.
GLIBC-SA-2024-0003:
===================
syslog: Integer overflow in __vsyslog_internal (CVE-2023-6780)
__vsyslog_internal calculated a buffer size by adding two integers, but
did not first check if the addition would overflow.

- A build bug was found with 1.6.0 if --enable-read-both-confs was set in the configure.
A commit fixing this has been released and converted into a patch for IPFire. This
will end up in the next pam release version and the IPFire patch can then be removed.
