According to the versions of the libdwarf package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
dwarf_leb.c in libdwarf allows attackers to cause a denial of service (SIGSEGV).(CVE-2015-8538)
The dwarf_dealloc function in libdwarf before 20160923 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted DWARF section.(CVE-2016-5043)
The dwarf_get_aranges_list function in libdwarf before 20160923 allows remote attackers to cause a denial of service (infinite loop and crash) via a crafted DWARF section.(CVE-2016-5042)
libdwarf before 20160923 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a large length value in a compilation unit header.(CVE-2016-5040)
The get_attr_value function in libdwarf before 20160923 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted object with all-bits on.(CVE-2016-5039)
The dwarf_get_macro_startend_file function in dwarf_macro5.c in libdwarf before 20160923 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted string offset for .debug_str.(CVE-2016-5038)
The dump_block function in print_sections.c in libdwarf before 20160923 allows remote attackers to cause a denial of service (out-of-bounds read) via crafted frame data.(CVE-2016-5036)
dwarf_elf_access.c in libdwarf before 20160923 allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted file, related to relocation records.(CVE-2016-5034)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
