Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU50329

Risk: Low

CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2019-25013

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition in GNU C Library within the iconv feature when processing multi-byte input sequences in the EUC-KR encoding. A remote attacker can pass specially crafted input to the application, trigger out-of-bounds read error and perform a denial of service (DoS) attack.

Mitigation

Update the affected package glibc to the latest version.

2) Infinite loop

EUVDB-ID: #VU50404

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2020-27618

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

3) Reachable Assertion

EUVDB-ID: #VU49670

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2020-29562

CWE-ID: CWE-617 - Reachable Assertion

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a reachable assertion when converting UCS4 text containing an irreversible character in the iconv function in the GNU C Library (aka glibc or libc6). A remote attacker can pass specially crafted data to the library, trigger an assertion failure and preform a denial of service attack.

Mitigation

Update the affected package glibc to the latest version.
