Christopher Angelo PhillipsandAlex Goodman f15c3343e2 Pin Gguff lib to prevent dropping packages (#5447)
* test: catalog GGUF models larger than the header

gguf-parser-go v0.26.3+ rejects a header whose tensors declare more data than follows it. Syft parses only a 50 MB copy of each model, so any larger model is dropped.

* fix: bound GGUF tensor info before the parser reads it

The header pre-scan stopped after the metadata KVs and left tensor infos to gguf-parser-go. Older releases of the library allocate whatever length a tensor name declares, so a tiny file could force a multi-GB allocation, or a fatal out of memory that panic recovery can't catch.

- tensor names are bounded like metadata keys (non-empty, length limit, shared string budget)
- dimension count is capped at `GGML_MAX_DIMS`
- a tensor count larger than the header now fails at EOF in the pre-scan

* fix: give the GGUF header copy the model's real size

The cataloger copies at most 50 MB of a model and parses that copy. Newer gguf-parser-go releases check the tensor data the header declares against the file size, so the truncated copy of any larger model was rejected.

- after the header is validated, the copy is extended to the size the resolver reports for the model, leaving the tail as a hole the parser never reads
- sources that report no size (OCI model artifacts today) keep the old behavior

* chore(deps): restore gguf-parser-go v0.26.4

The header copy now carries the model's real size, so the pin to v0.26.0 and its dependabot ignore are no longer needed. This also brings back upstream's string and array length bounds, and the library's own `IsNumeric`.

* fix: keep the extended GGUF header copy sparse on Windows

NTFS reserves disk for the full length of a file extended with truncate unless the file is marked sparse, so cataloging a large model on Windows reserved the model's size in the temp dir until cleanup.

- the header copy is marked sparse (`FSCTL_SET_SPARSE`) before it is extended
- if the filesystem can't make it sparse (FAT32, exFAT), the copy is not extended, and models larger than it fail to parse as before
- `golang.org/x/sys` moves from an indirect to a direct dependency

Alex Goodman d0e1e7be05 Harden cataloger parsers against truncated input (do not panic) (#5355)
* fix(javascript): don't panic on a yarn v1 lockfile line missing its value

A v1 `yarn.lock` dependency line without a version constraint, or a
`version`/`resolved`/`integrity` line without a value, indexed past the end of
the split line. Such dependencies are now skipped and empty fields left empty.

* fix(alpine): don't panic on an apk db ACL or checksum line before its entry

An `M:`, `a:` or `Z:` line that comes before any directory or file entry in
`lib/apk/db/installed` indexed `files[-1]`. Such a line is now skipped.

* fix(erlang): don't panic on a truncated rebar.lock or .app file

The term parser read past the end of the input when a file ended mid-term:
whitespace only, an unclosed list, a lone `<`, or a comment ending in `\r`.
These now return an "unexpected end of input" error.

* fix(lua): don't panic on a truncated .rockspec

The rockspec parser read past the end of the input when a file ended mid-statement:
a lone `[`, an unclosed `[[...]]` value or `[...]` index, or a `local` assignment cut off
before its `=`, value, or line end. These now return an "unexpected end of input" error.

* fix(spdx): don't panic on an opam checksum without an algorithm

The opam cataloger stores checksums verbatim, so a malformed one reached the SPDX encoder and panicked there, outside the cataloger's recover. Checksums without an `=` are now skipped.

* test: fuzz every generic cataloger parser

One fuzz target over every glob-selected parser in the capabilities data, run
through its cataloger task. Each input must not panic, must finish in time and
must keep allocations proportional to its size. Seeds come from each parser's
testdata plus the string literals in its package.

* test: scan malformed inputs under memory and time limits

A directory of small malformed files (deep nesting, oversized declared counts,
truncation, type mismatches, non-finite floats) is scanned by the CLI with a
memory limit and an RSS ceiling. The scan must exit 0 and write an SBOM.

* test: stop a fuzz input once its live heap passes the allocation limit

The allocation check only ran after the parser returned, so an input on its way to exhausting memory ran the machine into swap first. The harness now polls the live heap while the parser runs and panics past the same limit, which the fuzz engine saves as a crasher.

* fix: bound nesting depth and error context in the erlang and lua parsers

- a deeply nested rebar.lock or .rockspec overflowed the goroutine stack, which is fatal rather than a recoverable panic, so one file could take down the whole scan. Both parsers now stop at 1000 levels with an error.
- parse errors echoed whole input lines into the SBOM as unknowns, and lua appended another copy at every nesting level. `PrintError` now clips to a window around the error column, and lua decorates once at the top.
- the Podfile.lock error no longer echoes the pod entry.

* test: close ways the malformed-input checks could pass quietly

- a ctx-aware parser hitting the fuzz timeout now fails the input instead of racing the hard deadline
- the heap watchdog measures growth from a post-GC baseline rather than an absolute process-wide number
- a saved fuzz input naming a target that no longer exists fails instead of being skipped
- the CLI malformed-input scan fails on a recovered parser panic, not only on a non-zero exit

Alex Goodman b5e85c3ea5 chore: migrate fixtures to testdata (#4651)
* migrate fixtures to testdata

Signed-off-by: Alex Goodman <wagoodman@users.noreply.github.com>

* fix: correct broken symlinks after testdata migration

The migration from test-fixtures to testdata broke several symlinks:
- elf-test-fixtures symlinks pointed to old test-fixtures paths
- elf-test-fixtures needed to be renamed to elf-testdata
- image-pkg-coverage symlink pointed to test-fixtures instead of testdata

* fix: add gitignore negation for jar/zip fixtures in test/cli

The jar and zip files in test/cli/testdata/image-unknowns were being
gitignored by the root .gitignore patterns. This caused them to be
untracked and not included when building docker images in CI, resulting
in Test_Unknowns failures since the test expects errors from corrupt
archive files that weren't present.

Add a .gitignore in test/cli/testdata to negate the exclusions for
these specific test fixture files.

* fix: add go-shlex dependency for testdata manager tool

The manager tool in syft/pkg/cataloger/binary/testdata/ imports
go-shlex, but since it's in a testdata directory, Go doesn't track
its dependencies. This caused CI failures when go.mod didn't
explicitly list the dependency.

* refactor: move binary classifier manager to internal/

Move the manager tool from testdata/manager to internal/manager so
that Go properly tracks its dependencies. Code in testdata directories
is ignored by Go for dependency tracking, which caused CI failures
when go.mod didn't explicitly list transitive dependencies.

This is a cleaner solution than manually adding dependencies to go.mod
for code that happens to live in testdata.

* fix: add gitignore negations for test fixtures blocked by root patterns

Multiple test fixtures were being blocked by root-level gitignore patterns
like bin/, *.jar, *.tar, and *.exe. This adds targeted .gitignore files with
negation patterns to allow these specific test fixtures to be tracked:

- syft/linux/testdata/os/busybox/bin/busybox (blocked by bin/)
- syft/pkg/cataloger/java/testdata/corrupt/example.{jar,tar} (blocked by *.jar, *.tar)
- syft/pkg/cataloger/binary/testdata/classifiers/snippets/go-version-hint/**/bin/go (blocked by bin/)
- syft/pkg/cataloger/bitnami/testdata/no-rel/.../bin/redis-server (blocked by bin/)

Also updates the bitnami test expectation to include the newly required
.gitignore files in the test fixture.
