Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU16338
Risk: Low
CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
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 to version 2.31.1.
Vulnerable software versionsBinutils: 2.20.0 - 2.31
External linkshttp://sourceware.org/bugzilla/show_bug.cgi?id=23942
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
CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
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 to version 2.31.1.
Vulnerable software versionsBinutils: 2.20.0 - 2.31
External linkshttp://sourceware.org/bugzilla/show_bug.cgi?id=23932
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.
3) Memory leak
EUVDB-ID: #VU16344
Risk: Low
CVSSv3.1: 3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C]
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 to version 2.31.1.
Vulnerable software versionsBinutils: 2.31
External linkshttp://sourceware.org/bugzilla/show_bug.cgi?id=23952
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) Integer overflow
EUVDB-ID: #VU16695
Risk: Low
CVSSv3.1: 7.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-1000876
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The vulnerability exists due to integer overflow in objdump, bfd_get_dynamic_reloc_upper_bound,bfd_canonicalize_dynamic_reloc. A local attacker can trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
