libcurl's ASN1 parser has this utf8asn1str() function used for parsing an ASN.1 UTF-8 string. Itcan detect an invalid field and return error. Unfortunately, when doing so it also invokes `free()` on a 4 byte localstack buffer. Most modern malloc implementations detect this error and immediately abort. Some however accept the input pointer and add that memory to its list of available chunks. This leads to the overwriting of nearby stack memory. The content of the overwrite is decided by the `free()` implementation; likely to be memory pointers and a set of flags. The most likely outcome of exploting this flaw is a crash, although it cannot be ruled out that more serious results can be had in special circumstances.

The remote Windows host is missing security update 5044285. It is, therefore, affected by multiple vulnerabilities

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.
