GLib\u0026apos;s code was separated from GTK, so it can be used by software other than GNOME and has been developed in parallel ever since.\r\n\r\nSecurity Fix(es):\r\n\r\nAn issue was discovered in GNOME GLib before 2.66.7 and 2.67.x before 2.67.4. If g_byte_array_new_take() was called with a buffer of 4GB or more on a 64-bit platform, the length would be truncated modulo 2**32, causing unintended length truncation.(CVE-2021-27218)\r\n\r\nAn issue was discovered in GNOME GLib before 2.66.6 and 2.67.x before 2.67.3. The function g_bytes_new has an integer overflow on 64-bit platforms due to an implicit cast from 64 bits to 32 bits. The overflow could potentially lead to memory corruption.(CVE-2021-27219)\n\n** DISPUTED ** GNOME GLib before 2.65.3 has an integer overflow, that might lead to an out-of-bounds write, in g_option_group_add_entries. NOTE: the vendor's position is \"Realistically this is not a security issue. The standard pattern is for callers to provide a static list of option entries in a fixed number of calls to g_option_group_add_entries().\" The researcher states that this pattern is undocumented.(CVE-2020-35457)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS","name":"glib2","purl":"pkg:rpm/openEuler/glib2\u0026distro=openEuler-20.03-LTS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.62.5-4.oe1"}]}],"ecosystem_specific":{"aarch64":["glib2-2.62.5-4.oe1.aarch64.rpm","glib2-debuginfo-2.62.5-4.oe1.aarch64.rpm","glib2-debugsource-2.62.5-4.oe1.aarch64.rpm","glib2-devel-2.62.5-4.oe1.aarch64.rpm"],"noarch":["glib2-help-2.62.5-4.oe1.noarch.rpm"],"src":["glib2-2.62.5-4.oe1.src.rpm"],"x86_64":["glib2-debugsource-2.62.5-4.oe1.x86_64.rpm","glib2-debuginfo-2.62.5-4.oe1.x86_64.rpm","glib2-2.62.5-4.oe1.x86_64.rpm","glib2-devel-2.62.5-4.oe1.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://openeuler.org/en/security/safety-bulletin/detail.html?id=openEuler-SA-2021-1106"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-27218"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-27219"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-35457"}],"database_specific":{"severity":"High"}}
