[Fedora-i18n-bugs] [Bug 1543306] New: broken %postun scriptlet in ibus-libs package
by bugzilla＠redhat.com
https://bugzilla.redhat.com/show_bug.cgi?id=1543306
Bug ID: 1543306
Summary: broken %postun scriptlet in ibus-libs package
Product: Fedora
Version: 27
Component: ibus
Assignee: tfujiwar(a)redhat.com
Reporter: mattias.ellert(a)physics.uu.se
QA Contact: extras-qa(a)fedoraproject.org
CC: i18n-bugs(a)lists.fedoraproject.org,
shawn.p.huang(a)gmail.com, tfujiwar(a)redhat.com
Description of problem:
When updating the ibus-libs package the postun scriptlet fails and emits an
error:
Non-fatal POSTUN scriptlet failur in rpm package ibus-libs
Version-Release number of selected component (if applicable):
ibus-libs-1.5.17-5.fc27.x86_64 (and others)
How reproducible:
Always.
Steps to Reproduce:
1. Update ibus-libs (using a method that doesn's silently hide errors)
2. See the error message
Actual results:
You can see that there is an issue using the command
$ echo ---- ; rpm -q --scripts ibus-libs; echo ----
----
postinstall program: /sbin/ldconfig
postuninstall scriptlet (using /sbin/ldconfig):
# FIXME: no version number
----
Expected results:
What you expect is the following:
$ echo ---- ; rpm -q --scripts -p
results_ibus/1.5.17/7.fc28/ibus-libs-1.5.17-7.fc27.x86_64.rpm ; echo ----
----
postinstall program: /sbin/ldconfig
postuninstall program: /sbin/ldconfig
----
I.e. The %postun script should be empty, like the %post script is. The FIXME
comment in the specfile is currently placed in the %postun scriptlet, and
/sbin/ldconfig does not understand it and throws an error.
Additional info:
This can be fixed by moving the FIXME comment into the %files section:
diff --git a/ibus.spec b/ibus.spec
index b0ac4ca..8ff21f7 100644
--- a/ibus.spec
+++ b/ibus.spec

The rpm used in the "Expected results" section was built with this change.

Indeed that is. you're right. thanks for explanation and suggestion.

--- Comment #1 from Jakub Jelinek <jakub(a)redhat.com> ---
There is nothing weird on it, you overflow an buffer. Before filing bugs try
to your package with -fsanitize=address and/or -fsanitize=undefined.
static MConverter *converter;
static char buffer_for_converter[4096]; /* Currently, if preedit strings or
candidate strings over this buffer
size, they will simply ignore. */
...
static char *
convert_mtext2str(MText *mtext)
{
mconv_rebind_buffer(converter, (unsigned char *)buffer_for_converter,
sizeof(buffer_for_converter));
mconv_encode(converter, mtext);
buffer_for_converter[converter->nbytes] = 0;
return uim_strdup(buffer_for_converter);
}
So, you call first mconv_rebind_buffer which sets internal->bufsize to 4096,
then try to encode something. If it is really long, it will encode at most
that bufsize characters and set converter->nbytes to 4096. Then in
buffer_for_converter[converter->nbytes] = 0;
you overflow the buffer and because converter pointer happens to be adjacent
with -O2 right after it, you overwrite the last significant byte of it.
Guess either you need to pass sizeof(buffer_for_converter)-1 to
mconv_rebind_buffer, so that there is a place for the terminating '\0', or that
plus bump buffer_for_converter size to 4096+1.
