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

    When curl is told to use the Certificate Status Request TLS extension, often referred to as OCSP stapling,     to verify that the server certificate is valid, it might fail to detect some OCSP problems and instead     wrongly consider the response as fine.  If the returned status reports another error than 'revoked' (like     for example 'unauthorized') it is not treated as a bad certficate.(CVE-2024-8096)

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

    When curl is told to use the Certificate Status Request TLS extension, often referred to as OCSP stapling,     to verify that the server certificate is valid, it might fail to detect some OCSP problems and instead     wrongly consider the response as fine.  If the returned status reports another error than 'revoked' (like     for example 'unauthorized') it is not treated as a bad certficate.(CVE-2024-8096)

    When curl is asked to use HSTS, the expiry time for a subdomain might overwrite a parent domain's cache     entry, making it end sooner or later than otherwise intended. This affects curl using applications that     enable HSTS and use URLs with the insecure `HTTP://` scheme and perform transfers with hosts like     `x.example.com` as well as `example.com` where the first host is a subdomain of the second host. (The HSTS     cache either needs to have been populated manually or there needs to have been previous HTTPS accesses     done as the cache needs to have entries for the domains involved to trigger this problem.) When     `x.example.com` responds with `Strict-Transport-Security:` headers, this bug can make the subdomain's     expiry timeout *bleed over* and get set for the parent domain `example.com` in curl's HSTS cache. The     result of a triggered bug is that HTTP accesses to `example.com` get converted to HTTPS for a different     period of time than what was asked for by the origin server. If `example.com` for example stops supporting     HTTPS at its expiry time, curl might then fail to access `http://example.com` until the (wrongly set)     timeout expires. This bug can also expire the parent's entry *earlier*, thus making curl inadvertently     switch back to insecure HTTP earlier than otherwise intended.(CVE-2024-9681)

    Package        : curl     Version        : 7.74.0-1.3+deb11u14     CVE ID         : CVE-2024-8096


    curl a command line tool for transferring data with URL syntax was     affected by CVE-2024-8096. When the TLS backend is GnuTLS, curl may     incorrectly handle OCSP stapling. If the OCSP status reports an error     other than revoked (e.g., unauthorized), it is not treated as a     bad certificate, potentially allowing invalid certificates to be     considered valid.

    For Debian 11 bullseye, this problem has been fixed in version     7.74.0-1.3+deb11u14.

    We recommend that you upgrade your curl packages.

According to its self-reported version, the Nessus Network Monitor running on the remote host is prior to 6.5.0. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2024-17 advisory.

  - Nessus Network Monitor leverages third-party software to help provide underlying functionality. Several of     the third-party components (OpenSSL, expat, curl, and libxml2)were found to contain vulnerabilities,     and updated versions have been made available by the providers.Out of caution and in line with best     practice, Tenable has opted to upgrade these components to address the potential impact of the issues.
    Nessus Network Monitor 6.5.0 updates OpenSSL to version 3.0.15, expat to version 2.6.3, curl to version     8.10.0, and libxml2 to to version 2.13.1 to address the identified vulnerabilities.Additionally, one     separate vulnerability was discovered, reported and fixed:A stored cross site scripting vulnerability     exists in Nessus Network Monitor where an authenticated, privileged local attacker could inject arbitrary     code into the NNM UI via the local CLI. - CVE-2024-9158 Tenable has released Nessus Network Monitor 6.5.0     to address these issues. The installation files can be obtained from the Tenable Downloads Portal     (https://www.tenable.com/downloads/nessus-network-monitor).

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

    libcurl's ASN1 parser code has the `GTime2str()` function, used for parsing an ASN.1 Generalized Time     field. If given an syntactically incorrect field, the parser might end up using -1 for the length of the
    *time fraction*, leading to a `strlen()` getting performed on a pointer to a heap buffer area that is not     (purposely) null terminated.This flaw most likely leads to a crash, but can also lead to heap contents     getting returned to the application when     [CURLINFO_CERTINFO](https://curl.se/libcurl/c/CURLINFO_CERTINFO.html) is used.(CVE-2024-7264)

    When curl is told to use the Certificate Status Request TLS extension, often referred to as OCSP stapling,     to verify that the server certificate is valid, it might fail to detect some OCSP problems and instead     wrongly consider the response as fine.  If the returned status reports another error than 'revoked' (like     for example 'unauthorized') it is not treated as a bad certficate.(CVE-2024-8096)

The remote NewStart CGSL host, running version MAIN 7.02, has curl packages installed that are affected by multiple vulnerabilities:

  - CVE-2023-38546 is a cookie injection vulnerability in the curl_easy_duphandle(), a function in libcurl     that duplicates easy handles.  When duplicating an easy handle, if cookies are enabled, the duplicated     easy handle will not duplicate the cookies themselves, but would instead set the filename to none.'     Therefore, when the duplicated easy handle is subsequently used, if a source was not set for the cookies,     libcurl would attempt to load them from the file named none' on the disk.  This vulnerability is rated     low, as the various conditions required for exploitation are unlikely.  (CVE-2023-38546)

  - This flaw allows an attacker to insert cookies at will into a running program using libcurl, if the     specific series of conditions are met. libcurl performs transfers. In its API, an application creates     easy handles that are the individual handles for single transfers. libcurl provides a function call that     duplicates en easy handle called     [curl_easy_duphandle](https://curl.se/libcurl/c/curl_easy_duphandle.html). If a transfer has cookies     enabled when the handle is duplicated, the cookie-enable state is also cloned - but without cloning the     actual cookies. If the source handle did not read any cookies from a specific file on disk, the cloned     version of the handle would instead store the file name as `none` (using the four ASCII letters, no     quotes). Subsequent use of the cloned handle that does not explicitly set a source to load cookies from     would then inadvertently load cookies from a file named `none` - if such a file exists and is readable in     the current directory of the program using libcurl. And if using the correct file format of course.
    (CVE-2023-38546)

  - CVE-2023-38545 is a heap-based buffer overflow vulnerability in the SOCKS5 proxy handshake in libcurl and     curl.  When curl is given a hostname to pass along to a SOCKS5 proxy that is greater than 255 bytes in     length, it will switch to local name resolution in order to resolve the address before passing it on to     the SOCKS5 proxy. However, due to a bug introduced in 2020, this local name resolution could fail due to a     slow SOCKS5 handshake, causing curl to pass on the hostname greater than 255 bytes in length into the     target buffer, leading to a heap overflow.  The advisory for CVE-2023-38545 gives an example exploitation     scenario of a malicious HTTPS server redirecting to a specially crafted URL. While it might seem that an     attacker would need to influence the slowness of the SOCKS5 handshake, the advisory states that server     latency is likely slow enough to trigger this bug. (CVE-2023-38545)

  - This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to     pass along the host name to the SOCKS5 proxy to allow that to resolve the address instead of it getting     done by curl itself, the maximum length that host name can be is 255 bytes. If the host name is detected     to be longer, curl switches to local name resolving and instead passes on the resolved address only. Due     to this bug, the local variable that means let the host resolve the name could get the wrong value     during a slow SOCKS5 handshake, and contrary to the intention, copy the too long host name to the target     buffer instead of copying just the resolved address there. The target buffer being a heap based buffer,     and the host name coming from the URL that curl has been told to operate with. (CVE-2023-38545)

  - When curl retrieves an HTTP response, it stores the incoming headers so that they can be accessed later     via the libcurl headers API. However, curl did not have a limit in how many or how large headers it would     accept in a response, allowing a malicious server to stream an endless series of headers and eventually     cause curl to run out of heap memory. (CVE-2023-38039)
