Bug ID: 24891
Summary: objdump memory leaks when parsing malformed archive
Product: binutils
Version: 2.33 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: vincent.ulitzsch at gmail dot com
Target Milestone: ---
Created attachment 11942
--> https://sourceware.org/bugzilla/attachment.cgi?id=11942&action=edit
A file that causes the memory leak for objdump when being called like this:
objdump -x leak
objdump has several memory leaks when reading a malformed archive. The
allocations in questions seem to happen in archive.c, when opening a nested
file:
/* It's not an element of a nested archive;
open the external file as a bfd. */
n_bfd = open_nested_file (filename, archive);
The n_bdf struct has several members that are not freed, for example:
n_bfd->filename = xstrdup (filename);
Attached is a file that triggers the memory leaks. Find below an ASAN trace
that should help with debugging:
[vincent@vincent build-binutils]$ ./binutils/objdump -x
