CVE-2026-93566 Io.netty/netty-codec-http: netty: http request smuggling due to control characters in the chunk-size line

A flaw was found in Netty. A remote attacker could exploit this by sending a specially crafted HTTP request that includes control characters within the chunk-size line. This bypasses the intended strict validation, allowing the attacker to inject arbitrary HTTP requests. This vulnerability can le...

CVE-2026-93566

Netty (io.netty/netty-codec-http) is vulnerable to HTTP request smuggling due to a flaw in chunk-size line validation. The method HttpObjectDecoder#checkChunkExtensions only invokes the strict validator HttpChunkLineValidatingByteProcessor when a chunk extension (;) is present. When no extension ...

CVE-2026-93574: Inconsistent Interpretation of HTTP Requests

A flaw was found in Netty's netty-codec-http component. A remote attacker could exploit this vulnerability by sending a specially crafted HTTP/1.1 chunk-size token that includes post-digit whitespace. This incorrect parsing of the chunk size can lead to HTTP request smuggling. This allows an...

CVE-2026-61720: Integer Underflow (Wrap or Wraparound)

FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.5.0 until 2.5.6, the SF2 parser computes the DMOD modulator count as chunk.size / SFMODSIZE - 1 without rejecting chunks smaller than one record. A crafted SF2 file containing a zero-sized DMOD chunk makes the...

CVE-2026-73639

Imager::File::PNG versions from 1.003 before 1.004 for Perl write past the end of the row buffer reading a PNG with a tRNS transparency chunk in readdirect8. With a tRNS chunk, readdirect8 adds an alpha channel to the image it creates but still sizes the row buffer from the original channel count...

CVE-2026-73639

The Imager::File::PNG Perl module (versions 1.003 to 1.004 ) is vulnerable to an out-of-bounds write when processing a PNG file containing a tRNS transparency chunk in the read_direct8 function. The root cause is that read_direct8 adds an alpha channel but fails to resize the row buffer according...
