Description

This security bulletin contains information about 2 vulnerabilities.

1) Resource exhaustion (CVE-ID: CVE-2025-58183)

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 perform a denial of service (DoS) attack.

The vulnerability exists in archive/tar due to the tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A remote attacker can pass a specially crafted archive to the application and perform a denial of service (DoS) attack.

2) Improper input validation (CVE-ID: CVE-2026-34986)

CWE-ID: CWE-20 - Improper input validation

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 improper input validation in JWE decryption in key_wrap.go when processing a JWE object with a key wrapping algorithm and an empty encrypted_key field. A remote attacker can send a specially crafted JWE object to cause a denial of service.

The issue is reachable through ParseEncrypted(), ParseEncryptedJSON(), or ParseEncryptedCompact() followed by Decrypt(), and applications are affected only if accepted key algorithms include key wrapping algorithms.
