Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) NULL pointer dereference
EUVDB-ID: #VU11088
Risk: Low
CVSSv3.1: 3.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-7570
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the assign_file_positions_for_non_load_sections function due to the improper processing of crafted Executable and Linkable Format (ELF) files that contain a RELRO segment that lacks a matching LOAD segment. A remote attacker can send a specially crafted ELF file, trick the victim into opening it, trigger NULL pointer dereference and cause the service to crash.
Install update from vendor's website.
Vulnerable software versionsBinutils: 2.30

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
2) Integer overflow
EUVDB-ID: #VU11089
Risk: Low
CVSSv3.1: 3.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-7568
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the parse_die function that is defined in the dwarf1.c source code file due to the improper processing of crafted Executable and Linkable Format (ELF) files that contain corrupted dwarf1 debug information. A remote attacker can send a specially crafted ELF file, trick the victim into opening it, trigger integer overflow and cause the service to crash.

3) Memory corruption
EUVDB-ID: #VU11090
Risk: Low
CVSSv3.1: 3.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-7569
CWE-ID:
CWE-191 - Integer underflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the dwarf2.c source code file due to the improper processing of crafted Executable and Linkable Format (ELF) files that contain a corrupted DWARF FORM block. A remote attacker can send a specially crafted ELF file, trick the victim into opening it, trigger integer overflow or underflow and cause the service to crash.
