IBM Guardium Data Protection 12.2 is affected by a command injection vulnerability in the GIM bundle import functionality. An authenticated attacker can provide a crafted GIM bundle that causes attacker-controlled arguments to be passed to the tar command, resulting in arbitrary command execution with elevated privileges on the Central Manager.

IBM Server Firmware FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, FW1060.00 through FW1060.81, and FW950.00 through FW950.H3 is affected by a vulnerability in the ASMI web interface. An unauthenticated attacker on the management network can send a malformed HTTPS request to ASMI, causing the web server to crash with possible memory corruption and generate an error log. The ASMI web interface will restart automatically; however, repeated exploitation could result in a sustained loss of access to the ASMI management interface, resulting in an integrity and availability impact.

IBM Informix Dynamic Server 14.10 could allow a local user on the system to log into the Informix server as administrator without a password.

A flaw was found in Undertow that can cause remote denial of service attacks. When the server uses the FormEncodedDataDefinition.doParse(StreamSourceChannel) method to parse large form data encoding with application/x-www-form-urlencoded, the method will cause an OutOfMemory issue. This flaw allows unauthorized users to cause a remote denial of service (DoS) attack.

Summary

It is possible to put data in front of an LZMA-encoded byte stream without detecting the situation while reading the header. This can lead to increased memory consumption because the current implementation allocates the full decoding buffer directly after reading the header. The LZMA header doesn't include a magic number or has a checksum to detect such an issue according to the specification.

Note that the code recognizes the issue later while reading the stream, but at this time the memory allocation has already been done.

Mitigations

The release v0.5.15 includes following mitigations:

- The ReaderConfig DictCap field is now interpreted as a limit for the dictionary size. - The default is 2 Gigabytes - 1 byte (2^31-1 bytes). - Users can check with the [Reader.Header] method what the actual values are in their LZMA files and set a smaller limit using ReaderConfig. - The dictionary size will not exceed the larger of the file size and the minimum dictionary size. This is another measure to prevent huge memory allocations for the dictionary. - The code supports stream sizes only up to a pebibyte (1024^5).

Note that the original v0.5.14 version had a compiler error for 32 bit platforms, which has been fixed by v0.5.15.

Methods affected

Only software that uses lzma.NewReader or lzma.ReaderConfig.NewReader is affected. There is no issue for software using the xz functionality.

I thank @GregoryBuligin for his report, which is provided below.

Summary When unpacking a large number of LZMA archives, even in a single goroutine, if the first byte of the archive file is 0 (a zero byte added to the beginning), an error writeMatch: distance out of range occurs. Memory consumption spikes sharply, and the GC clearly cannot handle this situation.

Details Judging by the error writeMatch: distance out of range, the problems occur in the code around this function. https://github.com/ulikunitz/xz/blob/c8314b8f21e9c5e25b52da07544cac14db277e89/lzma/decoderdict.go#L81

PoC Run a function similar to this one in 1 or several goroutines on a multitude of LZMA archives that have a 0 (a zero byte) added to the beginning. const ProjectLocalPath = "some/path" const TmpDir = "tmp"

func UnpackLZMA(lzmaFile string) error { file, err := os.Open(lzmaFile) if err != nil { return err } defer file.Close()

reader, err := lzma.NewReader(bufio.NewReader(file)) if err != nil { return err }

tmpFile, err := os.CreateTemp(TmpDir, TmpLZMAPrefix) if err != nil { return err } defer func() { tmpFile.Close() = os.Remove(tmpFile.Name()) }()

sha256Hasher := sha256.New() multiWriter := io.MultiWriter(tmpFile, sha256Hasher)

if , err = io.Copy(multiWriter, reader); err != nil { return err }

unpackHash := hex.EncodeToString(sha256Hasher.Sum(nil)) unpackDir := filepath.Join( ProjectLocalPath, unpackHash[:2], ) = os.MkdirAll(unpackDir, DirPerm)

unpackPath := filepath.Join(unpackDir, unpackHash)

return os.Rename(tmpFile.Name(), unpackPath) }

Impact Servers with a small amount of RAM that download and unpack a large number of unverified LZMA archives

A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file.

Summary

In the fallback extraction path for source distributions, pip used Python’s tarfile module without verifying that symbolic/hard link targets resolve inside the intended extraction directory. A malicious sdist can include links that escape the target directory and overwrite arbitrary files on the invoking host during pip install.

Impact

Successful exploitation enables arbitrary file overwrite outside the build/extraction directory on the machine running pip. This can be leveraged to tamper with configuration or startup files and may lead to further code execution depending on the environment, but the direct, guaranteed impact is integrity compromise on the vulnerable system.

Conditions

The issue is triggered when installing an attacker-controlled sdist (e.g., from an index or URL) and the fallback extraction code path is used. No special privileges are required beyond running pip install; active user action is necessary.

Remediation

The fix, while available as a patch that can be manually applied, has not yet been put into a numbered version but is planned for 25.3. Using a Python interpreter that implements the safe-extraction behavior described by PEP 706 provides additional defense in depth for other tarfile issues but is not a substitute for upgrading pip for this specific flaw.

Impact

urllib3 supports chained HTTP encoding algorithms for response content according to RFC 9110 (e.g., Content-Encoding: gzip, zstd).

However, the number of links in the decompression chain was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps leading to high CPU usage and massive memory allocation for the decompressed data.

Affected usages

Applications and libraries using urllib3 version 2.5.0 and earlier for HTTP requests to untrusted sources unless they disable content decoding explicitly.

Remediation

Upgrade to at least urllib3 v2.6.0 in which the library limits the number of links to 5.

If upgrading is not immediately possible, use preloadcontent=False and ensure that resp.headers["content-encoding"] contains a safe number of encodings before reading the response content.

Impact

urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once.

When streaming a compressed response, urllib3 can perform decoding or decompression based on the HTTP Content-Encoding header (e.g., gzip, deflate, br, or zstd). The library must read compressed data from the network and decompress it until the requested chunk size is met. Any resulting decompressed data that exceeds the requested amount is held in an internal buffer for the next read operation.

The decompression logic could cause urllib3 to fully decode a small amount of highly compressed data in a single operation. This can result in excessive resource consumption (high CPU usage and massive memory allocation for the decompressed data; CWE-409) on the client side, even if the application only requested a small chunk of data.

Affected usages

Applications and libraries using urllib3 version 2.5.0 and earlier to stream large compressed responses or content from untrusted sources.

stream(), read(amt=256), read1(amt=256), readchunked(amt=256), readinto(b) are examples of urllib3.HTTPResponse method calls using the affected logic unless decoding is disabled explicitly.

Remediation

Upgrade to at least urllib3 v2.6.0 in which the library avoids decompressing data that exceeds the requested amount.

If your environment contains a package facilitating the Brotli encoding, upgrade to at least Brotli 1.2.0 or brotlicffi 1.2.0.0 too. These versions are enforced by the urllib3[brotli] extra in the patched versions of urllib3.

DataStage on Cloud Pak for Data can allow a man-in-the-middle attacker to present a forged TLS certificate, intercept the connection, and capture the IAM bearer Authorization header automatically attached by the session adapter. The captured token grants full platform-scope tenant API access, enabling the attacker to read and manipulate the victim's DataStage projects, flows, assets, and pipeline definitions. This is client-side SDK code running on the user's own machine, so exploitation requires an external network interceptor rather than a co-tenant in the shared cluster.
