USN-8794-1: GLib vulnerabilities

Ubuntu Security Advisories
3 days 10 hours ago
It was discovered that GLib's GDBus authentication mechanism failed to enforce length limitations on data lines read from a client. An unauthenticated attacker could exploit this to cause a denial of service via resource exhaustion. (CVE-2026-15588) It was discovered that the xdgmime library in GLib had a heap-based buffer overflow. An attacker-controlled MIME magic file could cause an out-of-bounds write on little-endian systems. (CVE-2026-16118) It was discovered that GLib had an off-by-one error in the GVariant serialiser. An attacker could use this to cause an out-of-bounds read, leading to information disclosure or a denial of service. (CVE-2026-58010) It was discovered that GLib had an out-of-bounds read in GDateTime. An attacker could use this to corrupt date output and cause a denial of service. (CVE-2026-58011) It was discovered that GLib's g_regex_replace() function had a buffer over-read when used with the G_REGEX_RAW flag. An attacker could use this to cause information disclosure or a denial of service. (CVE-2026-58012) It was discovered that GLib's GIOChannel had a buffer over-read when using a custom line terminator. An attacker could use this to cause information disclosure or a denial of service. (CVE-2026-58013) It was discovered that GLib's GKeyFile had an off-by-one error when loading a key file with an empty value. An attacker could use this to cause an out-of-bounds access or a denial of service. (CVE-2026-58014) It was discovered that GLib's DBUS_COOKIE_SHA1 authentication mechanism failed to validate the cookie_context parameter. A malicious D-Bus server could use this to read arbitrary files from the client. (CVE-2026-58015) It was discovered that GLib's D-Bus introspection XML parser had a state confusion issue. An attacker could use this to cause an out-of-bounds read and denial of service. (CVE-2026-58016)
