Description
This security bulletin contains information about 5 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.
