Description

This security bulletin contains information about 10 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2018-16062)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 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:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in dwarf_getaranges in dwarf_getaranges.c in libdw in elfutils before 2018-08-18. A remote attacker can perform a denial of service (heap-based buffer over-read) via a crafted file.


2) Out-of-bounds read (CVE-ID: CVE-2018-16403)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 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:Green


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

libdw in elfutils 0.173 checks the end of the attributes list incorrectly in dwarf_getabbrev in dwarf_getabbrev.c and dwarf_hasattr in dwarf_hasattr.c, leading to a heap-based buffer over-read and an application crash.


3) Segmentation fault (CVE-ID: CVE-2018-18310)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear


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

The vulnerability exists in the dwfl_segment_report_module.c source code file in the libdwfl library due to improper handling of Executable and Linkable Format (ELF) files. A local attacker can send an ELF file that submits malicious input, execute the eu-stack command, trigger a segmentation fault and cause the affected application to crash.


4) Null pointer dereference (CVE-ID: CVE-2018-18520)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 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:P/U:Clear


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to due to improper handling of Executable and Linkable Format (ELF) files by the elf_end function, as defined in the size.c source code file. A remote attacker can trick the victim into opening a specially crafted ELF file that submits malicious input, trigger NULL pointer dereference and cause application to crash.


5) Divide by zero (CVE-ID: CVE-2018-18521)

CWE-ID: CWE-369 - Divide By Zero

CVSSv4: 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:P/U:Clear


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to due to improper handling of Executable and Linkable Format (ELF) files by the arlib_add_symbols function, as defined in the arlib.c source code file. A remote attacker can trick the victim into opening a specially crafted ELF file that submits malicious input, trigger a divide-by-zero condition and cause application to crash.


6) Heap-based out-of-bounds read (CVE-ID: CVE-2019-7149)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 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:P/U:Clear


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper handling of Executable and Linkable Format (ELF) files by the read_srclines function, as defined in the dwarf_getsrclines.c source code file. A remote attacker can trick the victim into opening a specially crafted an ELF file that submits malicious input, trigger a heap-based buffer over-read condition and cause the affected application to crash, resulting in a DoS condition.


7) Segmentation fault (CVE-ID: CVE-2019-7150)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 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:P/U:Clear


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient sanitization of user-supplied input by the elf64_xlatetom function as defined in the libelf/elf32_xlatetom.c source code file. A remote attacker can trick the victim into opening a specially crafted file that submits malicious input, trigger a segmentation fault and cause the affected application to crash, resulting in a DoS condition.


8) Segmentation fault (CVE-ID: CVE-2019-7665)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 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:P/U:Clear


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

The vulnerability exists in the ebl_core_note function due to improper check if the values of a NT_PLATFORM core file note is a zero-terminated string. A remote attacker can trick the victim into opening an Executable and Linkable Format (ELF) file that submits malicious input, trigger a segmentation fault that causes the affected application to crash, resulting in a DoS condition. 


9) Out-of-bounds write (CVE-ID: CVE-2020-21047)

CWE-ID: CWE-787 - Out-of-bounds write

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


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the libcpu component. A remote attacker can create a specially crafted file, trick the victim into opening it and perform a denial of service (DoS) attack.


10) Infinite loop (CVE-ID: CVE-2021-33294)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

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


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop within the handle_symtab() function in readelf.c. A remote attacker can consume all available system resources and trigger denial of service condition.
