openSUSE Security Update : mbedtls (openSUSE-2016-903)

medium Nessus Plugin ID 92625

Language:

Synopsis

The remote openSUSE host is missing a security update.

Description

This mbedtls update to version 1.3.17 fixes the following issues :

Security issues fixed :

 - Fix missing padding length check in mbedtls_rsa_rsaes_pkcs1_v15_decrypt required by PKCS1 v2.2

 - Fix a potential integer underflow to buffer overread in mbedtls_rsa_rsaes_oaep_decrypt. It is not triggerable remotely in SSL/TLS.

 - Fix potential integer overflow to buffer overflow in mbedtls_rsa_rsaes_pkcs1_v15_encrypt and mbedtls_rsa_rsaes_oaep_encrypt

Bugs fixed :

 - Fix bug in mbedtls_mpi_add_mpi() that caused wrong results when the three arguments where the same (in-place doubling). Found and fixed by Janos Follath.
 #309

 - Fix issue in Makefile that prevented building using armar.

 - Fix issue that caused a hang up when generating RSA keys of odd bitlength

 - Fix bug in mbedtls_rsa_rsaes_pkcs1_v15_encrypt that made NULL pointer dereference possible.

 - Fix issue that caused a crash if invalid curves were passed to mbedtls_ssl_conf_curves. #373

Further changes :

 - On ARM platforms, when compiling with -O0 with GCC, Clang or armcc5, don't use the optimized assembly for bignum multiplication. This removes the need to pass

-fomit-frame-pointer to avoid a build error with -O0.

 - Disabled SSLv3 in the default configuration.

 - Fix non-compliance server extension handling. Extensions for SSLv3 are now ignored, as required by RFC6101.

Solution

Update the affected mbedtls packages.
