CVE-2020-11728

An issue was discovered in DAViCal Andrew's Web Libraries (AWL)
through 0.60. Session management does not use a sufficiently
hard-to-guess session key. Anyone who can guess the microsecond time
(and the incrementing session_id) can impersonate a session.

CVE-2020-11729

An issue was discovered in DAViCal Andrew's Web Libraries (AWL)
through 0.60. Long-term session cookies, uses to provide long-term
session continuity, are not generated securely, enabling a brute-force
attack that may be successful.

For Debian 8 'Jessie', these problems have been fixed in version
0.55-1+deb8u1.

We recommend that you upgrade your awl packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
