Astra Linux – Vulnerability in Waitress

Waitress version 1.3.1 allows for the smuggling of requests by sending the Content-Length header twice. Waitress would fold the two Content-Length headers together, and since it cannot convert the now comma-separated values into integers, it internally sets the Content-Length to 0. If two...

Astra Linux – Vulnerability in libproxy

In libproxy, the url.cpp module in version 0.4.15 is vulnerable to a buffer overflow when PAC is enabled. This vulnerability was confirmed by using a large PAC file that was sent without a Content-length header...

CVE-2026-80048

A flaw was found in sssd-kcm. A local user or process able to connect to the sssd-kcm UNIX socket can exploit this vulnerability. By sending a large request length header and then stalling the connection, an attacker can cause the system to preallocate significant memory. This leads to memory...

CVE-2026-106453

The yawkat LZ4 Java library is vulnerable to a memory exhaustion issue in versions prior to 1.11.2 . The LZ4DecompressorWithLength component incorrectly trusts a four-byte decompressed-length header from the input without prior validation. An attacker can provide a small (e.g., five-byte) input t...

CVE-2026-106453 yawkat LZ4 Java: LZ4DecompressorWithLength allocates the unvalidated size from the 4-byte length header, so a 5-byte input triggers a 1 GiB allocation and OutOfMemoryError

yawkat LZ4 Java provides LZ4 compression for Java. Prior to 1.11.2, LZ4DecompressorWithLength uses getDecompressedLength to trust the four-byte decompressed-length header before validating the compressed input, allowing a five-byte attacker-supplied input whose header declares a large output size...

CVE-2026-58268: Memory Allocation with Excessive Size Value

SIPGO is a library for writing SIP services in the GO language. Prior to 1.4.1, ParserStream.parseSingle in sip/parserstream.go allocates a SIP body buffer from the client-controlled Content-Length header before ParseMaxMessageLength is enforced. An unauthenticated peer can send a stream-transpor...

GHSA-8H4C-X2WG-6XP8 Http4s Ember accepts Transfer-Encoding combined with Content-Length (CL.TE request smuggling)

Summary Ember's HTTP/1.1 request parser does not reject a message that carries both a Transfer-Encoding and a Content-Length header. RFC 9112 §6.1 requires a server to treat such a message as a framing error and close the connection. An intermediary that follows the RFC's CL-strip-and-forward pat...
