gitsign --verify panics on empty-certificate PKCS7 and exits 0, bypassing exit-code callers

5.4 MediumFix available

Gitsign is a keyless Sigstore to signing tool for Git commits with your a GitHub / OIDC identity. From 0.4.0 to before 0.15.0, CertVerifier.Verify() in pkg/git/verifier.go unconditionally dereferences certs[0] after sd.GetCertificates() without checking the slice length. A CMS/PKCS7 signed message with an empty certificate set is a structurally valid DER payload; GetCertificates() returns an empty slice with no error, causing an immediate index-out-of-range panic. On the gitsign --verify code path (the GPG-compatible mode invoked by git verify-commit), the panic is silently recovered by internal/io/streams.go's Wrap() function, which returns nil instead of an error. main.go then exits with code 0, causing exit-code-only verification callers to interpret the failed verification as success. This vulnerability is fixed in 0.15.0.

Summary

CertVerifier.Verify() in pkg/git/verifier.go unconditionally dereferences certs[0] after sd.GetCertificates() without checking the slice length. A CMS/PKCS7 signed message with an empty certificate set is a structurally valid DER payload; GetCertificates() returns an empty slice with no error, causing an immediate index-out-of-range panic.

Severity

Medium (CVSS 3.1: 5.8)

CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L

  • Attack Vector: Network — attacker pushes a commit carrying a crafted signature to any accessible repository, or delivers the signature file out-of-band
  • Attack Complexity: Low — stripping certificates from a PKCS7 object requires only standard ASN.1 tooling
  • Privileges Required: None — writing to an accessible repo (or creating a repo a victim clones) is sufficient
  • User Interaction: Required — victim must run git verify-commit, gitsign --verify, or an equivalent verification step
  • Scope: Unchanged
  • Confidentiality Impact: None
  • Integrity Impact: Low — exit-code-only callers (scripts, some CI pipelines) treat the panicked verification as success; git's own status-fd path checks for GOODSIG and is therefore partially protected
  • Availability Impact: Low — the verification process aborts via panic on every invocation with such a signature

Affected Component

  • pkg/git/verifier.go — (*CertVerifier).Verify (line 114)
  • internal/io/streams.go — (*Streams).Wrap (lines 71–84, the recovery that returns nil on panic)

CWE

  • CWE-129: Improper Validation of Array Index
  • CWE-390: Detection of Error Condition Without Action Taken (panic swallowed, nil returned)

Description

Unconditional index dereference after GetCertificates

CertVerifier.Verify() parses the incoming signature as CMS/PKCS7 and calls GetCertificates() to extract the signer's certificate before any signature math takes place:

// pkg/git/verifier.go:109–114
certs, err := sd.GetCertificates()
if err != nil {
    return nil, fmt.Errorf("error getting signature certs: %w", err)
}
cert := certs[0]   // panic: index out of range if certs is empty

GetCertificates() delegates to sd.psd.X509Certificates() (the upstream smimesign/ietf-cms library). RFC 5652 §5.1 marks the certificates field in SignedData as OPTIONAL, and an empty or absent set is a structurally valid CMS message. The library returns (nil, nil) or ([]*, nil) for such a message — an empty slice with no error — so the length check on err is irrelevant:

// internal/fork/ietf-cms/signed_data.go:53–55
func (sd *SignedData) GetCertificates() ([]*x509.Certificate, error) {
    return sd.psd.X509Certificates()   // returns ([], nil) for empty cert set
}

There is no length guard anywhere between GetCertificates() and the certs[0] dereference.

Panic recovery silently returns exit 0

All root-command invocations (including gitsign --verify, which git calls for verify-commit) are wrapped by (*Streams).Wrap:

// internal/commands/root/root.go:69–95
RunE: func(cmd *cobra.Command, args []string) error {
    s := io.New(o.Config.LogPath)
    defer s.Close()
    return s.Wrap(func() error {     // panic recovery is here
        ...
        case o.FlagVerify:
            return commandVerify(o, s, args...)
        ...
    })
},

Wrap uses a bare recover() inside a defer:

// internal/io/streams.go:71–84
func (s *Streams) Wrap(fn func() error) error {
    defer func() {
        if r := recover(); r != nil {
            fmt.Fprintln(s.TTYOut, r,…
