Debian DLA-3044-1 : glib2.0 - LTS security update
medium Nessus Plugin ID 161906
Language:
Synopsis
The remote Debian host is missing one or more security-related updates.Description
The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3044 advisory.- An 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)
- An 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)
- An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also creates the target of the symlink as an empty file, which could conceivably have security relevance if the symlink is attacker-controlled. (If the path is a symlink to a file that already exists, then the contents of that file correctly remain unchanged.) (CVE-2021-28153)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade the glib2.0 packages.For Debian 9 stretch, these problems have been fixed in version 2.50.3-2+deb9u3.
