Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Unchecked Return Value
EUVDB-ID: #VU55301
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-28902
CWE-ID:
CWE-252 - Unchecked Return Value
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an unchecked return value in the "read_yin_container()" function. A remote attacker can run a specially crafted program to cause a denial of service condition.
MitigationUpdate the affected package libyang to the latest version.
