[PATCH] libdwfl: Sanity check partial core file data reads.

2018-10-14 Thread Mark Wielaard
There were two issues when reading note data from a core file. We didn't check if the data we already had in a buffer was big enough. And if we did get the data, we should check if we got everything, or just a part of the data. https://sourceware.org/bugzilla/show_bug.cgi?id=23752 Signed-off-by:

[PATCH] findtextrel: Check that sh_entsize isn't zero.

2018-10-14 Thread Mark Wielaard
A bogus ELF file could have sh_entsize as zero. Don't divide by zero, but just assume there are no entries in the section. https://sourceware.org/bugzilla/show_bug.cgi?id=23755 Signed-off-by: Mark Wielaard --- src/ChangeLog | 4 src/findtextrel.c | 23 +-- 2 files

[PATCH] ar: Assume epoch if ar_date is bogus.

2018-10-14 Thread Mark Wielaard
If the ar header contains a bogus ar_date then in verbose mode we would get a NULL pointer from localtime. Just assume the entry was created during the epoch. https://sourceware.org/bugzilla/show_bug.cgi?id=23754 Signed-off-by: Mark Wielaard --- src/ChangeLog | 4 src/ar.c | 10 +
