{"schemaVersion":3,"id":"USN-8794-1","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"glib2.0 vulnerabilities\n\nIt was discovered that GLib's GDBus authentication mechanism failed to\nenforce length limitations on data lines read from a client. An\nunauthenticated attacker could exploit this to cause a denial of service\nvia resource exhaustion. (CVE-2026-15588)\n\nIt was discovered that the xdgmime library in GLib had a heap-based\nbuffer overflow. An attacker-controlled MIME magic file could cause an\nout-of-bounds write on little-endian systems. (CVE-2026-16118)\n\nIt was discovered that GLib had an off-by-one error in the GVariant\nserialiser. An attacker could use this to cause an out-of-bounds read,\nleading to information disclosure or a denial of service.\n(CVE-2026-58010)\n\nIt was discovered that GLib had an out-of-bounds read in GDateTime. An\nattacker could use this to corrupt date output and cause a denial of\nservice. (CVE-2026-58011)\n\nIt was discovered that GLib's g_regex_replace() function had a buffer\nover-read when used with the G_REGEX_RAW flag. An attacker could use\nthis to cause information disclosure or a denial of service.\n(CVE-2026-58012)\n\nIt was discovered that GLib's GIOChannel had a buffer over-read when\nusing a custom line terminator. An attacker could use this to cause\ninformation disclosure or a denial of service. (CVE-2026-58013)\n\nIt was discovered that GLib's GKeyFile had an off-by-one error when\nloading a key file with an empty value. An attacker could use this to\ncause an out-of-bounds access or a denial of service. (CVE-2026-58014)\n\nIt was discovered that GLib's DBUS_COOKIE_SHA1 authentication mechanism\nfailed to validate the cookie_context parameter. A malicious D-Bus\nserver could use this to read arbitrary files from the client.\n(CVE-2026-58015)\n\nIt was discovered that GLib's D-Bus introspection XML parser had a\nstate confusion issue. An attacker could use this to cause an\nout-of-bounds read and denial of service.
