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...

HTTP Request Smuggling

Overview Affected versions of this package are vulnerable to HTTP Request Smuggling due to lenient parsing in the chunk decoder process. An attacker can bypass intermediary controls, poison caches, or hijack the request queue by crafting specially formatted chunked requests that exploit differenc...

Summary Ember's chunk decoder parses the size token leniently: it strips leading and trailing whitespace and accepts a leading + or - sign. RFC9112 §7.1 defines chunk-size = 1HEXDIG. An intermediary that parses the chunk boundary differently or rejects it will disagree with Ember on request...
