Name of the Vulnerable Software and Affected Versions
zlib versions on AlmaLinux8.2
Description
The zlib packages provide a general-purpose lossless data compression library used by many programs. Issues include incomplete raw streams production on s390x and a failed raw zlib test with DFLTCC LEVEL MASK set to 0x1ff. Additionally, there was a need to fix support for IBM Z hardware-accelerated deflate.
Recommendations
For AlmaLinux8.2, update the zlib package to a version that includes the fixes for the mentioned issues, specifically addressing the production of incomplete raw streams and the failed raw zlib test.
As a temporary workaround, consider restricting the use of zlib on s390x hardware until the update is applied.
