Description
This security bulletin contains information about 3 vulnerabilities.
1) Observable discrepancy (CVE-ID: CVE-2026-59640)
CWE-ID: CWE-203 - Observable discrepancy
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to recover information about encrypted OpenPGP data.
The vulnerability exists due to an oracle exposure in OpenPGP CFB quick-check processing when handling symmetric and session-key paths. A remote attacker can submit crafted encrypted data to recover information about encrypted OpenPGP data.
2) Resource exhaustion (CVE-ID: CVE-2026-59648)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to uncontrolled resource consumption in OpenPGP Argon2 S2K processing when honoring attacker-chosen memory and passes. A remote attacker can supply crafted OpenPGP data to cause a denial of service.
3) Uncontrolled Memory Allocation (CVE-ID: CVE-2026-59649)
CWE-ID: CWE-789 - Uncontrolled Memory Allocation
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to uncontrolled memory allocation in OpenPGP user-attribute subpacket parsing when processing a length bounded only by JVM max memory. A remote attacker can supply a crafted subpacket to cause a denial of service.
