When using in-repository authz rules with the AuthzSVNReposRelativeAccessFile option an unauthenticated remote client can take advantage of this flaw to cause a denial of service by sending a request for a non-existing repository URL. For the stable distribution (buster), this problem has been fixed in version 1.10.4-1+deb10u2. We recommend that you upgrade your subversion packages. For the detailed security status of subversion please refer to its security tracker page at: https://security-tracker.debian.org/tracker/subversion Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ - -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEERkRAmAjBceBVMd3uBUy48xNDz0QFAmAnuNtfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDQ2 NDQ0MDk4MDhDMTcxRTA1NTMxRERFRTA1NENCOEYzMTM0M0NGNDQACgkQBUy48xND z0TEgQ/7B/Q1myqwz2fbhOoIJBhhUj5h1rOumY75313o4oVie9DO2Wfdq8orjdW4 vq3XLFfdcGyrfrP+QpcKBLP9042o5YNvm7zMEQ4aABnsudEC5m18McJpzrPTB50H i2l0SBG0KTffRNziXmumqDZK/hiev9BDIBTi+MrX7aA6x6mHJHfHsq2YiLj0vluU ap240iT4Ds/0x8Gly0zPjcCWvtWVOfyvwSX9MIeNn7RpcyhXKysm++/fEwmmAkj8 Uu4toxIWzFB51lMxUkzjeIFhJlIvjYThcQ2ppSuocozTUUdVwSQfqO/HqxzzanoP fbUqdNuJ4pEaw1XbOkrUlvwznxXZJu2tHhwk8QQHwFjGAvis1egoDjbznAwmQLeL t82P/pBjcIMpbyusUGQ4d8m4RLGw/sFQUOJL9VkmdbokK3bZCf0MmwCC1dQQOhtP fDlnGdmvnVNjS0w/TdcVtXnf/9osY4+cHurQIAikRbesRRy0+GU7uwsMc7xbrHYJ CNJq4lkwyqhpcGTg3FIg76xtyVSnPRRptEFoh41ORxLOxpJ6YnC9MwkgQOWsjNUG n41adApEDGCHKuxBsu3oCDMnSal+zeK9i9sQHQMJl0myaRHbeRnPH2qXpO1/OAuI O16w2Jt+eF2OzQC2Nkr2fq9BZxv5tstsxeZqCPPE2YHfArAvkHg= =vgyS - -----END PGP SIGNATURE----- - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
