SUSE-SU-2026:23008-1 Security update for perl

This update for perl fixes the following issues - CVE-2025-15649: IO:Uncompress:Unzip propagates uncaught exception when parsing zip header with malformed DOS date bsc1266361. - CVE-2026-8376: heap buffer overflow when compiling regular expressions with a repeated fixed string on 32-bit builds...

Amazon Linux 2 : perl-IO-Compress, --advisory ALAS2-2026-3355 (ALAS-2026-3355)

The version of perl-IO-Compress installed on the remote host is prior to 2.061-2. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3355 advisory. IO::Uncompress::Unzip versions before 2.220 for Perl allow CPU exhaustion via per-byte read loop in fastForward...

Amazon Linux 2023 : perl-IO-Compress, perl-IO-Compress-tests (ALAS2023-2026-1825)

"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1825 advisory. IO::Uncompress::Unzip versions before 2.220 for Perl allow CPU exhaustion via per-byte read loop in fastForward. fastForward compares length $offset the digit count of the offset, 1 to 19...

CVE-2025-15649

A flaw was found in perl-IO-Compress. This vulnerability allows a remote attacker to cause a Denial of Service DoS by providing a specially crafted zip file. The IO::Uncompress::Unzip module, which is part of perl-IO-Compress, does not properly handle malformed date information within a zip file'...

AZL-89307 CVE-2026-48959 affecting package perl for versions less than 5.38.2-512

IO::Uncompress::Unzip versions before 2.220 for Perl allow CPU exhaustion via per-byte read loop in fastForward. fastForward compares length $offset the digit count of the offset, 1 to 19 against the chunk size $c instead of $offset itself, so $c shrinks from 16 KiB to 1-19 bytes per iteration...

IO::Uncompress::Unzip versions before 2.220 for Perl allow CPU exhaustion via per-byte read loop in fastForward. fastForward compares length $offset the digit count of the offset, 1 to 19 against the chunk size $c instead of $offset itself, so $c shrinks from 16 KiB to 1-19 bytes per iteration...

CVE-2026-48959

The IO::Uncompress::Unzip Perl module (versions before 2.220 ) is vulnerable to a CPU exhaustion attack. The root cause is located in the fastForward() function, which incorrectly compares the length of the $offset variable (a digit count between 1 and 19) against the chunk size $c, rather than c...
