EulerOS Virtualization 2.9.1 : glib2 (EulerOS-SA-2021-1712)

medium Nessus Plugin ID 148582

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the glib2 package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- 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)

- 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected glib2 packages.
