Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU16338
Risk: Low
CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-19931
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition on the target system.
The vulnerability exists due to heap-based buffer overflow in the bfd_elf32_swap_phdr_in function, as defined in the elfcode.h source code file when handling malicious input. A local attacker can supply a specially crafted file that may trigger memory corruption and cause the service to crash.
MitigationUpdate the affected package binutils to version 2.32-1.
Vulnerable software versionsArch Linux: All versions
CPE2.3 External linkshttps://security.archlinux.org/advisory/ASA-201906-3
Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Integer overflow
EUVDB-ID: #VU16339
Risk: Low
CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-19932
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition on the target system.
The vulnerability exists due to integer overflow in the IS_CONTAINED_BY_LMAfunction, as defined in the elf.c source code file when handling malicious input. A local attacker can map a section to a segment, trigger an infinite loop condition, resulting in a DoS condition.
MitigationUpdate the affected package binutils to version 2.32-1.

3) Memory leak
EUVDB-ID: #VU16344
Risk: Low
CVSSv4.0: 1.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2018-20002
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition on the target system.
The vulnerability exists due to memory leak in the _bfd_generic_read_minisymbols function in syms.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils. A local attacker can send specially crafted ELF file, consume excessive resources and cause the service to crash.
MitigationUpdate the affected package binutils to version 2.32-1.

Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
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.
4) Heap-based out-of-bounds read
EUVDB-ID: #VU17102
Risk: Low
CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-20712
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a heap-based buffer over-read in the function d_expression_1 in cp-demangle.c in GNU libiberty. A remote attacker can pass specially crafted data to the application, trigger segmentation faults and read contents of memory on the system.
MitigationUpdate the affected package binutils to version 2.32-1.
