Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 33 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2021-f3ebd7554c advisory.

 - radare2 4.5.0 misparses DWARF information in executable files, causing a segmentation fault in parse_typedef in type_dwarf.c via a malformed DW_AT_name in the .debug_info section. (CVE-2020-16269)

 - radare2 4.5.0 misparses signature information in PE files, causing a segmentation fault in r_x509_parse_algorithmidentifier in libr/util/x509.c. This is due to a malformed object identifier in IMAGE_DIRECTORY_ENTRY_SECURITY. (CVE-2020-17487)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected radare2 package.
