Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2019-12972)
The vulnerability allows an attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer over-read condition within the "_bfd_doprnt" function in the "bfd.c" file in the Binary File Descriptor (BFD) library. A local attacker can pass a malformed ELF binary to the affected application and perform a denial of service attack.
2) Integer overflow (CVE-ID: CVE-2019-14250)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in simple_object_elf_match() function in simple-object-elf.c. A remote attacker can use a specially crFted ELF file to trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Integer overflow (CVE-ID: CVE-2019-14444)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in apply_relocations() function in readelf.c. A remote attacker can create a specially crafted ELF file, trick the victim to use it, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Infinite loop (CVE-ID: CVE-2019-17450)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when processing ELF files within the find_abstract_instance() function in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd). A remote attacker can consume all available system resources and cause denial of service conditions.
5) Integer overflow (CVE-ID: CVE-2019-17451)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the _bfd_dwarf2_find_nearest_line() function in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd). A remote attacker can #CONDITION2#, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Out-of-bounds read (CVE-ID: CVE-2019-9074)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in bfd_getl32() function in libbfd.c within the libbfd library, distributed in GNU Binutils. A remote attacker can create a specially crafted Excel file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
7) Heap-based buffer overflow (CVE-ID: CVE-2019-9075)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in _bfd_archive_64_bit_slurp_armap() function in archive64.c within the libbfd library, distributed in GNU Binutils. A remote 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.
8) Heap-based buffer overflow (CVE-ID: CVE-2019-9077)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing MIPS option section within the process_mips_specific() function in readelf.c. A remote 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.
