Description
This security bulletin contains information about 2 vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2019-17451)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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.
2) Input validation error (CVE-ID: CVE-2019-1010204)
CWE-ID: CWE-20 - Improper input validation
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:P/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the improper processing of Executable Linkable Format (ELF) files with invalid "e_shoff" header fields in the "gold/fileread.cc:497" and "elfcpp/elfcpp_file.h:644" files. A remote attacker can trick a victim to open a specially crafted ELF file, cause an out-of-bounds read condition and perform a denial of service attack on the target system.
