Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Integer overflow
EUVDB-ID: #VU77081
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-33204
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 within the check_overflow() function in common.c. A remote attacker can trigger an integer overflow and execute arbitrary code on the target system.
Note, the vulnerability exists due to incomplete fix for #VU69196 (CVE-2022-39377).
Install updates from vendor's repository.

2) Buffer overflow
EUVDB-ID: #VU69196
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-39377
CWE-ID:
CWE-119 - Memory corruption
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 allocate_structures() function in sa_common.c . A remote attacker can trick the victim into running a malicious application on system with a vulnerable version of sysstat, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
