21) Memory corruption

EUVDB-ID: #VU11090

Risk: Low

CVSSv4.0: 2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2018-7569

CWE-ID: CWE-191 - Integer underflow

Exploit availability: No

Description

The 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.

Mitigation

Update the affected packages.
sys-devel/binutils to version: 2.30-r2

22) NULL pointer dereference

EUVDB-ID: #VU11088

Risk: Low

CVSSv4.0: 2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2018-7570

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The 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.

23) NULL pointer dereference

EUVDB-ID: #VU11310

Risk: Low

CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2018-7642

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to improper bounds checking when using the swap_std_reloc_in function, as defined in the aoutx.h source code file in the Binary File Descriptor (BFD) library. A remote attacker can submit a specially crafted ELF file, trigger NULL pointer dereference and cause the service to crash.

Mitigation

Update the affected packages.

Risk: Low

CVSSv4.0: 2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2018-7643

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the display_debug_ranges function due to the improper processing of crafted ELF files that contain DWARF information. A remote attacker can trick the victim into opening a specially crafted ELF file, trigger integer overflow and cause the service to crash.

Mitigation

25) Improper resource shutdown

EUVDB-ID: #VU11262

Risk: Low

CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2018-8945

CWE-ID: CWE-404 - Improper Resource Shutdown or Release

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.

The weakness exists in the bfd_section_from_shdr function due to improper bounds checking. A remote attacker can submit a specially crafted ELF file and cause the service to crash.
