read_ints function used when processing certain malformed Apple
Property List files in binary format.
CVE-2022-48565
An XML External Entity (XXE) issue was discovered. In order to
avoid possible vulnerabilities, the plistlib module no longer
accepts entity declarations in XML plist files.
CVE-2022-48566
Possible constant-time-defeating compiler optimisations were
discovered in the accumulator variable in hmac.compare_digest.
CVE-2023-40217
It was discovered that it might be possible to bypass some of the
protections implemented by the TLS handshake in the ssl.SSLSocket
class. For example, unauthenticated data might be read by a program
expecting data authenticated by client certificates.
For Debian 10 buster, these problems have been fixed in version
3.7.3-2+deb10u6.
We recommend that you upgrade your python3.7 packages.
