Hi,
The following vulnerability was published for scilab.
CVE-2022-30045[0]:
| An issue was discovered in libezxml.a in ezXML 0.8.6. The function
| ezxml_decode() performs incorrect memory handling while parsing
| crafted XML files, leading to a heap out-of-bounds read.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
For further information see:

https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-30045
Please adjust the affected versions in the BTS as needed.
While Scilab indeed ships ezxml.c, I am not sure how this can be exploited.
The code is probably only used to load scicos/xcos schema.
