Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU22494
Risk: High
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-17543
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the LZ4_write32 when performing archiving operation with LZ4_compress_fast. A remote attacker can pass specially crafted input to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected package lz4 to the latest version.
Vulnerable software versionsSUSE Linux Enterprise Software Development Kit: 12-SP5
lz4-debugsource: before 1.8.0-3.3.1
lz4-debuginfo: before 1.8.0-3.3.1
liblz4-1-debuginfo: before 1.8.0-3.3.1
liblz4-1: before 1.8.0-3.3.1

No. We are not aware of malware exploiting this vulnerability.
2) Integer overflow
EUVDB-ID: #VU53439
Risk: High
CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-3520
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the fast LZ compression algorithm library. A remote attacker can pass specially crafted archive, trick the victim into opening it, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected package lz4 to the latest version.
