Security Bulletin
This security bulletin contains one medium risk vulnerability.
EUVDB-ID: #VU50075
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-2021-3326
CWE-ID:
CWE-617 - Reachable Assertion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion within the iconv function in the GNU C Library (aka glibc or libc6) when processing invalid input sequences in the ISO-2022-JP-3 encoding. A remote attacker can pass specially crafted data to the application, trigger an assertion failure and crash the affected application.
Install updates from vendor's repository.
