According to the versions of the glib2 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - An issue was discovered in GNOME GLib before 2.66.6 and     2.67.x before 2.67.3. The function g_bytes_new has an     integer overflow on 64-bit platforms due to an implicit     cast from 64 bits to 32 bits. The overflow could     potentially lead to memory corruption.(CVE-2021-27219)

  - An issue was discovered in GNOME GLib before 2.66.7 and     2.67.x before 2.67.4. If g_byte_array_new_take() was     called with a buffer of 4GB or more on a 64-bit     platform, the length would be truncated modulo 2**32,     causing unintended length truncation.(CVE-2021-27218)

  - An issue was discovered in GNOME GLib before 2.66.8.
    When g_file_replace() is used with     G_FILE_CREATE_REPLACE_DESTINATION to replace a path     that is a dangling symlink, it incorrectly also creates     the target of the symlink as an empty file, which could     conceivably have security relevance if the symlink is     attacker-controlled. (If the path is a symlink to a     file that already exists, then the contents of that     file correctly remain unchanged.)(CVE-2021-28153)

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.

According to the versions of the glib2 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - ** DISPUTED ** GNOME GLib before 2.65.3 has an integer overflow, that might lead to an out-of-bounds     write, in g_option_group_add_entries. NOTE: the vendor's position is 'Realistically this is not a security     issue. The standard pattern is for callers to provide a static list of option entries in a fixed number of     calls to g_option_group_add_entries().' The researcher states that this pattern is undocumented.
    (CVE-2020-35457)

  - An issue was discovered in GNOME GLib before 2.66.7 and 2.67.x before 2.67.4. If g_byte_array_new_take()     was called with a buffer of 4GB or more on a 64-bit platform, the length would be truncated modulo 2**32,     causing unintended length truncation. (CVE-2021-27218)

The version of AOS installed on the remote host is prior to 6.0.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.0.1 advisory.

  - encoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service (invalid write     access and application crash) or possibly have unspecified other impact via a crafted UTF-8 character     sequence. (CVE-2021-26937)

  - Vulnerability in the Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition product of Oracle Java     SE (component: Libraries). Supported versions that are affected are Java SE: 7u291, 8u281, 11.0.10, 16;
    Java SE Embedded: 8u281; Oracle GraalVM Enterprise Edition: 19.3.5, 20.3.1.2 and 21.0.0.2. Difficult to     exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to     compromise Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition. Successful attacks require human     interaction from a person other than the attacker. Successful attacks of this vulnerability can result in     unauthorized creation, deletion or modification access to critical data or all Java SE, Java SE Embedded,     Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments     that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox     for security. (CVE-2021-2163)

  - In ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16, ISC DHCP 4.4.0 -> 4.4.2 (Other branches of ISC DHCP (i.e., releases     in the 4.0.x series or lower and releases in the 4.3.x series) are beyond their End-of-Life (EOL) and no     longer supported by ISC. From inspection it is clear that the defect is also present in releases from     those series, but they have not been officially tested for the vulnerability), The outcome of encountering     the defect while reading a lease that will trigger it varies, according to: the component being affected     (i.e., dhclient or dhcpd) whether the package was built as a 32-bit or 64-bit binary whether the compiler     flag -fstack-protection-strong was used when compiling In dhclient, ISC has not successfully reproduced     the error on a 64-bit system. However, on a 32-bit system it is possible to cause dhclient to crash when     reading an improper lease, which could cause network connectivity problems for an affected system due to     the absence of a running DHCP client process. In dhcpd, when run in DHCPv4 or DHCPv6 mode: if the dhcpd     server binary was built for a 32-bit architecture AND the -fstack-protection-strong flag was specified to     the compiler, dhcpd may exit while parsing a lease file containing an objectionable lease, resulting in     lack of service to clients. Additionally, the offending lease and the lease immediately following it in     the lease database may be improperly deleted. if the dhcpd server binary was built for a 64-bit     architecture OR if the -fstack-protection-strong compiler flag was NOT specified, the crash will not     occur, but it is possible for the offending lease and the lease which immediately followed it to be     improperly deleted. (CVE-2021-25217)

  - Vulnerability in the Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition product of Oracle Java     SE (component: Libraries). Supported versions that are affected are Java SE: 7u291, 8u281, 11.0.10, 16;
    Java SE Embedded: 8u281; Oracle GraalVM Enterprise Edition: 19.3.5, 20.3.1.2 and 21.0.0.2. Difficult to     exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to     compromise Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition. Successful attacks of this     vulnerability can result in unauthorized creation, deletion or modification access to critical data or all     Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability     applies to Java deployments that load and run untrusted code (e.g., code that comes from the internet) and     rely on the Java sandbox for security. It can also be exploited by supplying untrusted data to APIs in the     specified Component. (CVE-2021-2161)

  - A flaw was found in Nettle in versions before 3.7.2, where several Nettle signature verification functions     (GOST DSA, EDDSA & ECDSA) result in the Elliptic Curve Cryptography point (ECC) multiply function being     called with out-of-range scalers, possibly resulting in incorrect results. This flaw allows an attacker to     force an invalid signature, causing an assertion failure or possible validation. The highest threat to     this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-20305)

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

The version of AOS installed on the remote host is prior to 5.20.2. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.20.2 advisory.

  - A flaw was found in the Routing decision classifier in the Linux kernel's Traffic Control networking     subsystem in the way it handled changing of classification filters, leading to a use-after-free condition.
    This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat     from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3715)

  - Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP     transfer-encoding request header in some circumstances leading to the possibility to request smuggling     when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if     the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding;
    and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.
    (CVE-2021-33037)
