|
| Hi,
|
|
|
|
|
| interesting crash with libmagic from file-5.28 used by rpmbuild or better
|
|
| its librpmbuild.so.3. See attached backtrace. It looks like strlcpy()
|
|
| runs on a NULL pointer as source. As well as it is not clrear why an
|
|
| ascii file like apefooter_8h__incl.md5 with a MD5 sum without line terminat=
|
|
| or
|
|
| does cause the libmagic to do an uncompress:
|
|
|
|
|
| file /home/abuild/rpmbuild/BUILDROOT/taglib-1.11-0.x86_64/usr/share/doc/pa=
|
|
| ckages/libtag-devel/html/apefooter_8h__incl.md5
|
|
| /home/abuild/rpmbuild/BUILDROOT/taglib-1.11-0.x86_64/usr/share/doc/package=
|
|
| s/libtag-devel/html/apefooter_8h__incl.md5: ASCII text, with no line termin=

It has been fixed on HEAD:
