The remote CentOS Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the CESA-2023:5433 advisory.

  - 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)

  - A compromised content process could have provided malicious data in a `PathRecording` resulting in an out-     of-bounds write, leading to a potentially exploitable crash in a privileged process. This vulnerability     affects Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3. (CVE-2023-5169)

  - During Ion compilation, a Garbage Collection could have resulted in a use-after-free condition, allowing     an attacker to write two NUL bytes, and cause a potentially exploitable crash. This vulnerability affects     Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3. (CVE-2023-5171)

  - Memory safety bugs present in Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2. 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 < 118, Firefox ESR < 115.3, and     Thunderbird < 115.3. (CVE-2023-5176)

  - Heap buffer overflow in vp8 encoding in libvpx in Google Chrome prior to 117.0.5938.132 and libvpx 1.13.1     allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium     security severity: High) (CVE-2023-5217)

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)

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 Firefox ESR installed on the remote Windows host is prior to 115.0.2. It is, therefore, affected by a vulnerability as referenced in the mfsa2023-26 advisory.

  - During the worker lifecycle, a use-after-free condition could have occurred, which could have led to a     potentially exploitable crash. (CVE-2023-3600)
