Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU54478
Risk: Low
CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-20266
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the hdrblobInit() function in lib/header.c. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
MitigationUpdate the affected package rpm to the latest version.

2) Insufficient verification of data authenticity
EUVDB-ID: #VU54477
Risk: Medium
CVSSv4.0: 4.8 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-20271
CWE-ID:
CWE-345 - Insufficient Verification of Data Authenticity
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to an error in RPM's signature check functionality when reading package files. A remote attacker can create a specially crafted package with a modified signature header, trick the victim into installing and compromise the affected system.
Update the affected package rpm to the latest version.

3) Improper Verification of Cryptographic Signature
EUVDB-ID: #VU54479
Risk: Medium
CVSSv4.0: 2.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-3421
CWE-ID:
CWE-347 - Improper Verification of Cryptographic Signature
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service attack.
