Fedora Update Notification
FEDORA-2025-d93200cf16
2025-12-12 01:32:22.209029+00:00
--------------------------------------------------------------------------------

Name        : perl-Alien-Brotli
Product     : Fedora 43
Version     : 0.2.2
Release     : 11.fc43
URL         : http://metacpan.org/dist/Alien-Brotli
Summary     : Find and install the Brotli compressor
Description :
This distribution installs the brotli compressor, so that it can be used by
other distributions, and provides a way to find the executable.

--------------------------------------------------------------------------------
Update Information:

Update brotli to 1.2.0 and python-urllib3 to 2.6.1.
In python-urllib3:
Fixed a security issue where streaming API could improperly handle highly
  compressed HTTP content ("decompression bombs") leading to excessive resource
  consumption even when a small amount of data was requested. Reading small
  chunks of compressed data is safer and much more efficient now.
  (CVE-2025-66471 / `GHSA-2xpw-w6gg-jr37)
Fixed a security issue where an attacker could compose an HTTP response with
  virtually unlimited links in the Content-Encoding header, potentially
  leading to a denial of service (DoS) attack by exhausting system resources
  during decoding. The number of allowed chained encodings is now limited to 5.
  (CVE-2025-66418 / `GHSA-gm62-xv2j-4w53)
--------------------------------------------------------------------------------
ChangeLog:

* Wed Dec 10 2025 Miro Hrončok <mhroncok@redhat.com> - 0.2.2-11
- Rebuilt for brotli 1.2.0
