It typically compresses files to within 10% to 15% of the best available techniques (the PPM family of statistical compressors), whilst being around twice as fast at compression and six times faster at decompression.\r\n\r\nSecurity Fix(es):\n\nbzip2 contains an off‑by‑one error in the bzip2recover utility. When processing a specially crafted file, the application performs an out‑of‑bounds write to a global buffer, resulting in memory corruption and a crash (denial of service).\n\nThis issue was fixed in bzip2 patch 35d122a3df8b0cc4082a4d89fdc6ee99f375fe67(CVE-2026-42250)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP1","name":"bzip2","purl":"pkg:rpm/openEuler/bzip2&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.8-9.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["bzip2-1.0.8-9.oe2403sp1.aarch64.rpm","bzip2-debuginfo-1.0.8-9.oe2403sp1.aarch64.rpm","bzip2-debugsource-1.0.8-9.oe2403sp1.aarch64.rpm","bzip2-devel-1.0.8-9.oe2403sp1.aarch64.rpm"],"noarch":["bzip2-help-1.0.8-9.oe2403sp1.noarch.rpm"],"src":["bzip2-1.0.8-9.oe2403sp1.src.rpm"],"x86_64":["bzip2-1.0.8-9.oe2403sp1.x86_64.rpm","bzip2-debuginfo-1.0.8-9.oe2403sp1.x86_64.rpm","bzip2-debugsource-1.0.8-9.oe2403sp1.x86_64.rpm","bzip2-devel-1.0.8-9.oe2403sp1.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"bzip2","purl":"pkg:rpm/openEuler/bzip2&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.8-9.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["bzip2-1.0.8-9.oe2403sp3.aarch64.rpm","bzip2-debuginfo-1.0.8-9.oe2403sp3.aarch64.rpm","bzip2-debugsource-1.0.8-9.oe2403sp3.aarch64.rpm","bzip2-devel-1.0.8-9.oe2403sp3.aarch64.rpm"],"noarch":["bzip2-help-1.0.8-9.oe2403sp3.noarch.rpm"],"src":["bzip2-1.0.8-9.oe2403sp3.src.rpm"],"x86_64":["bzip2-1.0.8-9.oe2403sp3.x86_64.rpm","bzip2-debuginfo-1.0.8-9.oe2403sp3.x86_64.rpm","bzip2-debugsource-1.0.8-9.oe2403sp3.x86_64.rpm","bzip2-devel-1.0.8-9.oe2403sp3.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"bzip2","purl":"pkg:rpm/openEuler/bzip2&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.8-7.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["bzip2-1.0.8-7.oe2003sp4.aarch64.rpm","bzip2-debuginfo-1.0.8-7.oe2003sp4.aarch64.rpm","bzip2-debugsource-1.0.8-7.oe2003sp4.aarch64.rpm","bzip2-devel-1.0.8-7.oe2003sp4.aarch64.rpm"],"noarch":["bzip2-help-1.0.8-7.oe2003sp4.noarch.rpm"],"src":["bzip2-1.0.8-7.oe2003sp4.src.rpm"],"x86_64":["bzip2-1.0.8-7.oe2003sp4.x86_64.rpm","bzip2-debuginfo-1.0.8-7.oe2003sp4.x86_64.rpm","bzip2-debugsource-1.0.8-7.oe2003sp4.x86_64.rpm","bzip2-devel-1.0.8-7.oe2003sp4.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"bzip2","purl":"pkg:rpm/openEuler/bzip2&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.8-7.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["bzip2-1.0.8-7.oe2203sp4.aarch64.rpm","bzip2-debuginfo-1.0.8-7.oe2203sp4.aarch64.rpm","bzip2-debugsource-1.0.8-7.oe2203sp4.aarch64.rpm","bzip2-devel-1.0.8-7.oe2203sp4.aarch64.rpm"],"noarch":["bzip2-help-1.0.8-7.oe2203sp4.noarch.rpm"],"src":["bzip2-1.0.8-7.oe2203sp4.src.rpm"],"x86_64":["bzip2-1.0.8-7.oe2203sp4.x86_64.rpm","bzip2-debuginfo-1.0.8-7.oe2203sp4.x86_64.rpm","bzip2-debugsource-1.0.8-7.oe2203sp4.x86_64.rpm","bzip2-devel-1.0.8-7.oe2203sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2786"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42250"}],"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"}],"database_specific":{"severity":"Medium"}}
