CVE-2026-53659

http4k is a functional toolkit for Kotlin HTTP applications. Prior to 4.51.0.0, 5.42.0.0, and 6.49.0.0, ServerFilters.GZip, RequestFilters.GunZip, and the underlying Gzip request-body decompression functions impose no limit on decompressed size. An unauthenticated client can send a small...

CVE-2026-44162

fluent-plugin-s3 is an Amazon S3 input and output plugin for Fluentd. From 0.7.0 to 1.8.4, the ins3 input plugin reads the entire decompressed payload of gzip, lzma2, and lzop objects into memory without enforcing a decompressionsizelimit. An attacker with permission to upload objects to the...

CVE-2026-53659

http4k is a functional Kotlin HTTP toolkit. The vulnerability (CWE-409) exists in ServerFilters.GZip , RequestFilters.GunZip , and the underlying gzip decompression functions, which imposed no cap on decompressed size . An unauthenticated client can send a small gzip-encoded request body that exp...

Astra Linux – Vulnerability in Python 3.11, Python 3.7

A use-after-free UAF vulnerability could occur in the lzma.LZMADecompressor, bz2.BZ2Decompressor, and gzip.GzipFile classes when a memory allocation failure with a MemoryError occurs and the decompression instance is reused. This scenario can occur if the process is under memory pressure. The fix...

Astra Linux – Vulnerability in Jetty9

In Eclipse Jetty versions 9.4.0 to 9.4.56, a buffer can be released incorrectly when encountering a gzip error during the inflation of a request body. This can lead to corrupted data and/or inadvertent sharing of data between requests...

Astra Linux – Vulnerability in gzip, xz-utils

A arbitrary file writing vulnerability was discovered in the GNU gzip’s zgrep utility. When zgrep is applied to a file name chosen by the attacker e.g., a crafted file name, it can overwrite the content of the target file with an arbitrary file selected by the attacker. This flaw arises due to...

Astra Linux – Vulnerability in PHP 7.3

In PHP versions prior to 7.4.31, 8.0.24, and 8.1.11, the phar uncompressor code would recursively uncompress “quines” gzip files, resulting in an infinite loop...

tornado: Tornado: Denial of Service via uncontrolled gzip decompression memory consumption

A flaw was found in Tornado, a Python web framework and asynchronous networking library. Its gzip decompression routines process data in limited-size chunks but do not enforce an overall limit on the total accumulated decompressed data. This vulnerability allows a malicious server to consume...
