Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of firefox installed on the remote host is prior to 102.11.0-2. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2FIREFOX-2023-005 advisory.

- There exists a use after free/double free in libwebp. An attacker can use the ApplyFiltersAndEncode() function and loop through to free best.bw and assign best = trial pointer. The second loop will then return 0 because of an Out of memory error in VP8 encoder, the pointer is still assigned to trial and the AddressSanitizer will attempt a double free. (CVE-2023-1999)

- In multiple cases browser prompts could have been obscured by popups controlled by content. These could have led to potential user confusion and spoofing attacks. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11. (CVE-2023-32205)

- An out-of-bound read could have led to a crash in the RLBox Expat driver. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11. (CVE-2023-32206)

- A missing delay in popup notifications could have made it possible for an attacker to trick a user into granting permissions. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11. (CVE-2023-32207)

- 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 <code>datalist</code> 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)

- Mozilla developers and community members Gabriele Svelto, Andrew Osmond, Emily McDonough, Sebastian Hengst, Andrew McCreight and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 112 and Firefox ESR 102.10. 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 < 113, Firefox ESR < 102.11, and Thunderbird < 102.11. (CVE-2023-32215)

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