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 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)
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 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 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 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 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 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 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)
Unbound before 1.9.5 allows an integer overflow in sldns_str2wire_dname_buf_origin, leading to an out-of-bounds write. (CVE-2019-25034)
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 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)
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.
