{"id":"OESA-2026-2694","summary":"python3 security update","details":"Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems. New built-in modules are easily written in C or C++ (or other languages, depending on the chosen implementation). Python is also usable as an extension language for applications written in other languages that need easy-to-use scripting or automation interfaces.\r\n\r\nSecurity Fix(es):\n\ntarfile.data_filter could be bypassed using crafted link entries, including symlinks with empty or directory-like names, to redirect later archive members outside the intended extraction directory. This allowed a malicious tar archive to cause tarfile.extractall() to write files outside the destination directory, subject to the permissions of the extracting process.(CVE-2026-7774)\n\nbz2.BZ2Decompressor objects could be reused after a decompression error. If an application caught the resulting OSError and retried with the same decompressor, crafted input could cause the decompressor to resume from an invalid internal state and perform out-of-bounds writes to a stack buffer. This could crash the process when processing untrusted data.(CVE-2026-9669)","modified":"2026-06-24T13:30:06.209785169Z","published":"2026-06-24T13:10:00Z","upstream":["CVE-2026-7774","CVE-2026-9669"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2694"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-7774"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-9669"}],"affected":[{"package":{"name":"python3","ecosystem":"openEuler:24.03-LTS-SP1","purl":"pkg:rpm/openEuler/python3&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.11.6-31.oe2403sp1"}]}],"ecosystem_specific":{"noarch":["python3-help-3.11.6-31.oe2403sp1.noarch.rpm"],"x86_64":["python3-3.11.6-31.oe2403sp1.x86_64.rpm","python3-debug-3.11.6-31.oe2403sp1.x86_64.rpm","python3-debuginfo-3.11.6-31.oe2403sp1.x86_64.rpm","python3-debugsource-3.11.6-31.oe2403sp1.x86_64.rpm","python3-devel-3.11.6-31.oe2403sp1.x86_64.rpm","python3-tkinter-3.11.6-31.oe2403sp1.x86_64.rpm","python3-unversioned-command-3.11.6-31.oe2403sp1.x86_64.rpm"],"src":["python3-3.11.6-31.oe2403sp1.src.rpm"],"aarch64":["python3-3.11.6-31.oe2403sp1.aarch64.rpm","python3-debug-3.11.6-31.oe2403sp1.aarch64.rpm","python3-debuginfo-3.11.6-31.oe2403sp1.aarch64.rpm","python3-debugsource-3.11.6-31.oe2403sp1.aarch64.rpm","python3-devel-3.11.6-31.oe2403sp1.aarch64.rpm","python3-tkinter-3.11.6-31.oe2403sp1.aarch64.rpm","python3-unversioned-command-3.11.6-31.oe2403sp1.aarch64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-2694.json"}}],"schema_version":"1.7.5"}
