According to the versions of the unbound packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :
DISPUTED Unbound before 1.9.5 allows configuration injection in create_unbound_ad_servers.sh upon a successful man-in-the-middle attack against a cleartext HTTP session. NOTE: The vendor does not consider this a vulnerability of the Unbound software. create_unbound_ad_servers.sh is a contributed script from the community that facilitates automatic configuration creation. It is not part of the Unbound installation. (CVE-2019-25031)
DISPUTED Unbound before 1.9.5 allows an integer overflow in the regional allocator via regional_alloc. NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited. (CVE-2019-25032)
DISPUTED Unbound before 1.9.5 allows an integer overflow in the regional allocator via the ALIGN_UP macro. NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited. (CVE-2019-25033)
DISPUTED Unbound before 1.9.5 allows an integer overflow in sldns_str2wire_dname_buf_origin, leading to an out-of-bounds write. NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited. (CVE-2019-25034)
DISPUTED Unbound before 1.9.5 allows an out-of-bounds write in sldns_bget_token_par. NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited. (CVE-2019-25035)
DISPUTED Unbound before 1.9.5 allows an assertion failure and denial of service in synth_cname.
NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited. (CVE-2019-25036)
DISPUTED Unbound before 1.9.5 allows an assertion failure and denial of service in dname_pkt_copy via an invalid packet. NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited. (CVE-2019-25037)
DISPUTED Unbound before 1.9.5 allows an integer overflow in a size calculation in dnscrypt/dnscrypt.c. NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited. (CVE-2019-25038)
DISPUTED Unbound before 1.9.5 allows an integer overflow in a size calculation in respip/respip.c.
NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited. (CVE-2019-25039)
DISPUTED Unbound before 1.9.5 allows an infinite loop via a compressed name in dname_pkt_copy. NOTE:
The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited. (CVE-2019-25040)
DISPUTED Unbound before 1.9.5 allows an assertion failure via a compressed name in dname_pkt_copy.
NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited. (CVE-2019-25041)
DISPUTED Unbound before 1.9.5 allows an out-of-bounds write via a compressed name in rdata_copy.
NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited. (CVE-2019-25042)
