The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2485-1 advisory.
The _bfd_elf_parse_gnu_properties function in elf-properties.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, does not prevent negative pointers, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) or possibly have unspecified other impact via a crafted ELF file. (CVE-2017-16829)
In the coff_pointerize_aux function in coffgen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, an index is not validated, which allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted file, as demonstrated by objcopy of a COFF object. (CVE-2018-7208)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
