The remote CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2023:6162 advisory.

  - VP9 in libvpx before 1.13.1 mishandles widths, leading to a crash related to encoding. (CVE-2023-44488)

  - It was possible for certain browser prompts and dialogs to be activated or dismissed unintentionally by     the user due to an insufficient activation-delay. This vulnerability affects Firefox < 119, Firefox ESR <     115.4, and Thunderbird < 115.4.1. (CVE-2023-5721)

  - Drivers are not always robust to extremely large draw calls and in some cases this scenario could have led     to a crash. This vulnerability affects Firefox < 119, Firefox ESR < 115.4, and Thunderbird < 115.4.1.
    (CVE-2023-5724)

  - A malicious installed WebExtension could open arbitrary URLs, which under the right circumstance could be     leveraged to collect sensitive user data. This vulnerability affects Firefox < 119, Firefox ESR < 115.4,     and Thunderbird < 115.4.1. (CVE-2023-5725)

  - During garbage collection extra operations were performed on a object that should not be. This could have     led to a potentially exploitable crash. This vulnerability affects Firefox < 119, Firefox ESR < 115.4, and     Thunderbird < 115.4.1. (CVE-2023-5728)

  - Memory safety bugs present in Firefox 118, Firefox ESR 115.3, and Thunderbird 115.3. Some of these bugs     showed evidence of memory corruption and we presume that with enough effort some of these could have been     exploited to run arbitrary code. This vulnerability affects Firefox < 119, Firefox ESR < 115.4, and     Thunderbird < 115.4.1. (CVE-2023-5730)

  - An attacker could have created a malicious link using bidirectional characters to spoof the location in     the address bar when visited. This vulnerability affects Firefox < 117, Firefox ESR < 115.4, and     Thunderbird < 115.4.1. (CVE-2023-5732)

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

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

  - Integer overflow in libaom internal function img_alloc_helper can lead to heap buffer overflow. This     function can be reached via 3 callers: * Calling aom_img_alloc() with a large value of the d_w, d_h, or     align parameter may result in integer overflows in the calculations of buffer sizes and offsets and some     fields of the returned aom_image_t struct may be invalid. * Calling aom_img_wrap() with a large value of     the d_w, d_h, or align parameter may result in integer overflows in the calculations of buffer sizes and     offsets and some fields of the returned aom_image_t struct may be invalid. * Calling     aom_img_alloc_with_border() with a large value of the d_w, d_h, align, size_align, or border parameter may     result in integer overflows in the calculations of buffer sizes and offsets and some fields of the     returned aom_image_t struct may be invalid. (CVE-2024-5171)

  - A type checking bug would have led to invalid code being compiled. This vulnerability affects Firefox <     113, Firefox ESR < 102.11, and Thunderbird < 102.11. (CVE-2023-32211)

  - An attacker could have positioned a `datalist` element to obscure the address bar. This vulnerability     affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11. (CVE-2023-32212)

  - When reading a file, an uninitialized value could have been used as read limit. This vulnerability affects     Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11. (CVE-2023-32213)

  - During the worker lifecycle, a use-after-free condition could have occured, which could have led to a     potentially exploitable crash. This vulnerability affects Firefox < 115.0.2, Firefox ESR < 115.0.2, and     Thunderbird < 115.0.1. (CVE-2023-3600)
