All commands work transparently with both VCFs and BCFs, both uncompressed and BGZF-compressed. (This BCFtools includes the polysomy subcommand, which is implemented using the GNU Scientific Library. Hence this package is licensed according to the GNU General Public License, rather than the MIT license used when BCFtools is built without the polysomy subcommand.) -------------------------------------------------------------------------------- Update Information: Update to 1.23.1 -------------------------------------------------------------------------------- ChangeLog: * Thu Mar 19 2026 Rasmus Ory Nielsen - 1.23.1-1 - Updated to 1.23.1 - Removed patch now that issue 2495 is fixed upstream * Mon Jan 26 2026 Rasmus Ory Nielsen - 1.23-1 - Updated to 1.23 - Removed obsolete vcf_plugin_tests patch - Remove invalid `-errors` from PERL_LIBS to fix linker warnings * Mon Jan 26 2026 Jun Aruga - 1.15.1-17 - RISC-V has /lib64/lp64d/ symlink which confuses ldd. * Fri Jan 16 2026 Fedora Release Engineering - 1.15.1-16 - Rebuilt for https://fedoraproject.org/wiki/Fedora_44_Mass_Rebuild * Fri Jan 16 2026 Fedora Release Engineering - 1.15.1-15 - Rebuilt for https://fedoraproject.org/wiki/Fedora_44_Mass_Rebuild * Wed Jul 23 2025 Fedora Release Engineering - 1.15.1-14 - Rebuilt for https://fedoraproject.org/wiki/Fedora_43_Mass_Rebuild * Mon Jul 7 2025 JitkaPlesnikova - 1.15.1-13 - Perl 5.42 rebuild -------------------------------------------------------------------------------- References: [ 1 ] Bug #2448750 - CVE-2026-31962 htslib: htslib: Heap buffer overflow leading to arbitrary code execution via crafted CRAM file https://bugzilla.redhat.com/show_bug.cgi?id=2448750 [ 2 ] Bug #2448751 - CVE-2026-31965 htslib: HTSlib: Information disclosure or denial of service via out-of-bounds read in CRAM record processing https://bugzilla.redhat.com/show_bug.cgi?id=2448751 [ 3 ] Bug #2448755 - CVE-2026-31963 htslib: HTSlib: Arbitrary code execution via crafted CRAM file https://bugzilla.redhat.com/show_bug.cgi?id=2448755 [ 4 ] Bug #2448756 - CVE-2026-31964 htslib: HTSlib: Denial of Service via NULL pointer dereference in CRAM decoding https://bugzilla.redhat.com/show_bug.cgi?id=2448756 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
