Artifex MuJS v1.1.3 was discovered to contain a heap buffer overflow which is caused by conflicting JumpList of nested try/finally statements.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Artifex MuJS v1.1.3 was discovered to contain a heap buffer overflow which is caused by conflicting     JumpList of nested try/finally statements. (CVE-2021-45005)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7575-1 advisory.

    It was discovered that MuJS did not correctly handle try/finally statements, which could lead to a buffer     overflow. An attacker could possibly use this issue to cause a denial of service or execute

    arbitrary code. (CVE-2021-45005)

    Han Zheng discovered that MuJS did not correctly handle recursion, which could lead to stack exhaustion.
    An attacker could possibly use this issue to cause a denial of service. (CVE-2022-30974)

    Han Zheng discovered that MuJS did not correctly handle certain memory operations. An attacker could     possibly use this issue to cause a denial of service. (CVE-2022-30975)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The remote host is affected by the vulnerability described in GLSA-202405-06 (mujs: Multiple Vulnerabilities)

  - Artifex MuJS v1.1.3 was discovered to contain a heap buffer overflow which is caused by conflicting     JumpList of nested try/finally statements. (CVE-2021-45005)

  - compile in regexp.c in Artifex MuJS through 1.2.0 results in stack consumption because of unlimited     recursion, a different issue than CVE-2019-11413. (CVE-2022-30974)

  - In Artifex MuJS through 1.2.0, jsP_dumpsyntax in jsdump.c has a NULL pointer dereference, as demonstrated     by mujs-pp. (CVE-2022-30975)

  - A logical issue in O_getOwnPropertyDescriptor() in Artifex MuJS 1.0.0 through 1.3.x before 1.3.2 allows an     attacker to achieve Remote Code Execution through memory corruption, via the loading of a crafted     JavaScript file. (CVE-2022-44789)

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