NewStart CGSL MAIN 7.02 : libwebp Multiple Vulnerabilities (NS-SA-2025-0183)

high Nessus Plugin ID 242705

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

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

- Heap buffer overflow in libwebp in Google Chrome prior to 116.0.5845.187 and libwebp 1.3.2 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: Critical) (CVE-2023-4863)

- 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)

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

Solution

Upgrade the vulnerable CGSL libwebp packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
