Bug ID: 31379
Summary: alpha-dec-vms objdump use of uninitialized value
Product: binutils
Version: 2.43 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: amodra at gmail dot com
Target Milestone: ---
Created attachment 15366
--> https://sourceware.org/bugzilla/attachment.cgi?id=15366&action=edit
objdump -s fuzzer testcase
The attached testcase sees alpha_vms_object_p setting up a section via
_bfd_vms_slurp_egsd from an EGSD__C_PSC record. Contents for this section are
not read by alpha_vms_get_section_contents into memory allocated there, leading
to reads of ininitialized memory. Similar testcases can also result in huge
amounts of memory being allocated.
