Description Robert Frohl 2019-11-08 15:31:51 UTC
Problem Description:

 Due to incorrect data management Squid is vulnerable to a
 information disclosure when processing HTTP Digest
 Authentication.

__________________________________________________________________

Severity:

 Nonce tokens contain the raw byte value of a pointer which sits
 within heap memory allocation. This information reduces ASLR
 protections and may aid attackers isolating memory areas to
 target for remote code execution attacks.

__________________________________________________________________

Updated Packages:

 This bug is fixed by Squid version 4.9.

 In addition, a patch addressing this problem for the stable
 releases can be found in our patch archives:

Squid 4:
 <http://www.squid-cache.org/Versions/v4/changesets/squid-4-671ba97abe929156dc4c717ee52ad22fba0f7443.patch>

 If you are using a prepackaged version of Squid then please refer
 to the package vendor for availability information on updated
 packages.

__________________________________________________________________

Determining if your version is vulnerable:

 All Squid-2.x have not been checked.

 All Squid-3.x up to and including 3.5.28 are vulnerable.

 All Squid-4.x up to and including 4.8 are vulnerable.

__________________________________________________________________

Workarounds:

Either;

 Remove 'auth_param digest ...' configuration settings from
 squid.conf.

Or,

 Build Squid with --disable-auth-digest
