A malicious or compromised Flatpak repository could write attacker-controlled files outside /var/lib/flatpak as root. + GHSA-8qxj-x646-phcm: Fix writing outside working directory in `flatpak build-init`. A malicious or compromised SDK could write outside the intended working directory when a developer starts using it for a build. - d/p/GHSA-qrwq-7qwx-q9rp/*.patch: Fix local privilege escalation involving revokefs. A malicious local user could write files outside /var/lib/flatpak as root by tampering with OSTree objects after signature verification. - d/p/GHSA-8688-9x26-hhxj/*.patch: Fix a sandbox escape involving directories inside ~/.var/app/APP_ID. A malicious or compromised Flatpak app could write to arbitrary files outside its sandbox. - d/p/GHSA-99wv-m8rp-g58x/*.patch: Fix a sandbox escape involving the ld.so cache. A malicious or compromised Flatpak app could write files with a fixed name and limited control over content outside the sandbox. - d/p/GHSA-v2gw-v9h5-9q4x/*.patch: Fix local privilege escalation involving crafted OCI architecture names. A malicious local user on a system with an OCI remote configured (unusual on non-Fedora systems) could trick the flatpak-system-helper process into writing outside /var/lib/flatpak. - d/p/GHSA-w69g-9x8j-7p8f/*.patch: Fix reading outside sandbox involving crafted extension metadata. A malicious or compromised Flatpak app could find out whether specific files exist outside the sandbox. - d/p/GHSA-q4gr-vc25-57m5/*.patch: Fix anti-downgrade checks for components installed system-wide. A malicious local user with an active local login session could downgrade an app, runtime or extension to an older, known-vulnerable version and use this to attack other local users. - d/p/GHSA-jr92-2v97-wgvc/*.patch: Fix a buffer overflow when installing or updating from a malicious OCI registry, not believed to be practically exploitable on 64-bit systems. - d/p/hardening/*.patch: Harden file accesses against path traversal, fixing issues that were initially thought to be security vulnerabilities similar to those above, but on further analysis do not seem to be exploitable. - d/p/GHSA-r7hp-698j-2h6c/*.patch: Correct xdg-dbus-proxy rules for receiving selected AT-SPI broadcasts so that GTK accessibility features work as intended. Previously, these accessibility features only worked accidentally as a result of an xdg-dbus-proxy security issue, fixed in 0.1.8. * d/patches: Add additional bug fixes from upstream 1.16.x branch - d/p/subprojects-Ignore-.wraplock-file-generated-by-recent-Mes.patch, d/p/bwrap-Clarify-a-comment.patch, d/p/subprojects-Update-dbus-proxy.wrap-to-v0.1.7.patch: Resync with upstream source, no functional changes - d/p/dir-Use-flatpak_bwrap_child_setup_inherit_fds_cb-to-apply.patch: Silence a spurious warning when apps use the extra_data mechanism - d/p/portal-Actually-use-the-AppInfo-hash-table.patch: Fix a memory leak and potential rare crashes in flatpak-portal Checksums-Sha1: 23819bb80df3336957c6a48b2d9e8b8cb2d47237 3741 flatpak_1.16.6-1~deb13u2.dsc ba597a6fe31a0749cb3f8835b72885e5b235b9d2 76448 flatpak_1.16.6-1~deb13u2.debian.tar.xz 131e098bbf4d64f1f69a4ceb55f12949f12b4b87 15293 flatpak_1.16.6-1~deb13u2_source.buildinfo Checksums-Sha256: 5aa8c6319336226ac6638acd8df94b63bc27da4621a478f3e47e0f9f564c18de 3741 flatpak_1.16.6-1~deb13u2.dsc bac37dc8430afe688734263f7efecb8a9bfff6098011d24a1647b2f09c99d790 76448 flatpak_1.16.6-1~deb13u2.debian.tar.xz cd3a79eddc583a2c65b61a71f05b936bef12a05362d5caa2233b3e1ed7bf00f6 15293 flatpak_1.16.6-1~deb13u2_source.buildinfo Files: 4ca674bfa72b7210851606ff843ed90e 3741 admin optional flatpak_1.16.6-1~deb13u2.dsc 51eeccf1f9d601f93a4a2ca595a714fe 76448 admin optional flatpak_1.16.6-1~deb13u2.debian.tar.xz c295c3e06eaf5d5e5a86cfe665b6a27c 15293 admin optional flatpak_1.16.6-1~deb13u2_source.buildinfo -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEegc60a5pT6Jb/2LlI1wJnT6zMHYFAmp7OMQACgkQI1wJnT6z MHbM7BAAyWAr40Kt7lpDvCJmkCS1LcRTBexSBmchq8rrP0yeLQwoJ3KynC0lI7FO ZhwhmnqCeBu+s0X5dH409FYGV8SimHLWw7ihPnnqZUvc0bjEGidanULENxnb3r2G v5r6RrI93xUZDVkR3ZyrHBUV4i4WSZJD9dMKf91UWuFh2InPz2edIhi86nRkZSox r4VDn6/AArAJ5yfBOeV001AUOGwFVvCmzZzYmys1Bl0aTtHDeJrZu7aE3JIsf1li AeHxN7sul1Ti3hqtlglL7ISVsdNycgqqU8T4osTDDfOU5Xk2yGk97yePRuZ1Du4I p5h+3IWAQMoOsZy3eYnKALiObqtGmW8iZw4SYLdNOtPLmmlynvbcfffoEe6r9JCz 3ONRXTmu6KpwQFXVPx0oAN9z0sz8ynA8SeXxg4Q0YfsVA/+cT6PdAfzNezvFbEM8 yYn4MOgi3iI5XPx9UG2ecitUZAPjRbG3py7ey9k3qVuP7XcvI28umZ0opPPjHCZ9 AHZmIQHz9WYHsJSGxI8cvXgNYDp4SCSk3KWfj0Go+q/wvRW00FYW+2AiKELuNauN vY/cgKw4/xorvUYTzBRoy3e2YD0QHbAYgW6Z9UbxKgyp1gpeW9nxim8nNYFlPooK EVVffgpmXh8hX/FvX57s5/tZ7qzeVHN/uu4hqv4QdorQgW/rVRs= =d3BX -----END PGP SIGNATURE-----
