Source: libxml2
Version: 2.9.10+dfsg-5
Severity: important

Hi,
The following vulnerability was published for libxml2.
CVE-2020-24977[0]:
| GNOME project libxml2 v2.9.10 and earlier have a global Buffer
| Overflow vulnerability in xmlEncodeEntitiesInternal at
| libxml2/entities.c. The issue has been fixed in commit 8e7c20a1
| (20910-GITv2.9.10-103-g8e7c20a1).
Please note that the CVE description looks missleading, because
8e7c20a1 is not the fixing commit, rather [1]. There is some upstream
discussion but this appears to be really a issue for xmllint, and as
well present before the bisected commit in the upstream issue. That
said, it is marked no-dsa for buster still.
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:

Please adjust the affected versions in the BTS as needed.
Regards,
Salvatore
