Bug ID: 28763
Summary: SIGSEGV during processing of program headers
Product: binutils
Version: 2.37
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: nils_b...@t-online.de
Target Milestone: ---
Created attachment 13899
--> https://sourceware.org/bugzilla/attachment.cgi?id=13899&action=edit
The crashing input alongside a script to automatically reproduce the bug.
SIGSEGV during processing of program headers
# Description
During processing of the attached elf file via
```
readelf -a
$PWD/02f5bec64cda36a9941f7752571e5a41328f683542fa5b125bf03a8dd3c10fb0
```
an out-of-bounds read is triggered, which causes a SIGSEGV. The bug appears to
be located in the code responsible for parsing the program headers.
This allows an attacker to perform a denial of service and possibly opens up
other attack vectors if files from untrusted sources are processed.
For reproduction of the crash, I attach a script called ./reproduce.sh
alongside
the crashing input. If you need further details, please do not hesitate to ask.
# Version
The input was tested on branch binutils-2_37 of
git://sourceware.org/git/binutils-gdb.git commit
116a737f438d03a1bd6aa706b6ea0b4022f3b7e2.
