The remote CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2023:5477 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)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
