Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Improper Authorization
EUVDB-ID: #VU63747
Risk: High
CVSSv3.1: 8.3 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-26691
CWE-ID:
CWE-285 - Improper Authorization
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to an error in implementation of "Local" authorization mechanism. A remote attacker can authenticate as to CUPS as root/admin without the 32-byte secret key and execute arbitrary code on the system.
Update the affected packages.
net-print/cups to version: 2.4.7
Gentoo Linux: All versions
net-print/cups: before 2.4.7

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the local network (LAN).
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Off-by-one
EUVDB-ID: #VU80932
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-2023-4504
CWE-ID:
CWE-193 - Off-by-one Error
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to an off-by-one error when parsing Postscript objects within the scan_ps() function in cups/raster-interpret.c. A remote attacker can trigger pass a specially crafted PPD file to the affected application, trigger a 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 packages.
net-print/cups to version: 2.4.7
Gentoo Linux: All versions
net-print/cups: before 2.4.7
External linkshttp://security.gentoo.org/glsa/202402-17
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
3) Heap-based buffer overflow
EUVDB-ID: #VU76761
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-32324
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 format_log_line() function cups/string.c when the "loglevel" is set to "DEBUG". A remote attacker can pass specially crafted data to the daemon, trigger a 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 packages.
