Summary
gpgtar in GnuPG before 2.5.19 can allow file overwrite via crafted data in an archive. When extracting an untrusted archive with --directory (-C) into an existing directory containing a pre-existing symlink, gpgtar can follow that symlink and create or overwrite a file outside the selected extraction directory. The write is limited by the extraction user's filesystem permissions.
Risk Assessment
An attacker could trick a user into extracting a malicious archive, potentially overwriting files outside the target directory and damaging data or modifying configuration files. The risk does not apply when extracting into a fresh empty directory.
Recommendation
Update GnuPG to version 2.5.19 or later. Extract untrusted archives only into newly created, empty directories.
Other vulnerabilities in GnuPG
See all- CVE-2019-14855Low
A flaw in GnuPG before version 2.2.18 allows certificate signature forgery using SHA-1 collision attacks. An attacker can create forged certificate signatures, compromising authentication integrity.
- CVE-2026-24882High
In GnuPG before version 2.5.17, a stack-based buffer overflow exists in the tpm2daemon component during handling of the PKDECRYPT command for TPM-backed RSA and ECC keys.
- CVE-2026-24881High
In GnuPG before version 2.5.17, a crafted CMS (S/MIME) EnvelopedData message with an oversized wrapped session key can cause a stack-based buffer overflow in gpg-agent during PKDECRYPT--kem=CMS handling. This can lead to denial of service, but also memory corruption that could result in remote code execution.
- CVE-2025-68972Medium
In GnuPG through 2.4.8, if a signed message has \f at the end of a plaintext line, an adversary can construct a modified message that places additional text after the signed material, such that signature verification of the modified message succeeds (although an "invalid armor" message is printed during verification). This is related to use of \f as a marker to denote truncation of a long plaintext line.
Original NVD description (English source)
gpgtar in GnuPG before 2.5.19 can allow file overwrite via crafted data in an archive. When extracting an untrusted archive with --directory (aka -C) into an existing directory containing a pre-existing symlink, gpgtar can follow that symlink and create or overwrite a file outside the selected extraction directory. The write is limited by the extraction user's filesystem permissions. An archive extracted into a fresh empty directory does not have this risk.
