high Nessus Plugin ID 179556

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the libwebp package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libwebp packages.
