Beschreibung:	Summary: The remote host is missing an update for the 'mbedtls' package(s) announced via the referenced advisory. Vulnerability Insight: This update for mbedtls fixes the following security and non-security issues: - Update to 1.3.15 * Fix potential double free if ssl_set_psk() is called more than once and some allocation fails. Cannot be forced remotely. Found by Guido Vranken, Intelworks. * Fix potential heap corruption on windows when x509_crt_parse_path() is passed a path longer than 2GB. Cannot be triggered remotely. Found by Guido Vranken, Intelworks. * Fix potential buffer overflow in some asn1_write_xxx() functions. Cannot be triggered remotely unless you create X.509 certificates based on untrusted input or write keys of untrusted origin. Found by Guido Vranken, Intelworks. * The x509 max_pathlen constraint was not enforced on intermediate certificates. Found by Nicholas Wilson, fix and tests provided by Janos Follath. #280 and #319 * Self-signed certificates were not excluded from pathlen counting, resulting in some valid X.509 being incorrectly rejected. Found and fix provided by Janos Follath. #319 * Fix bug causing some handshakes to fail due to some non-fatal alerts not begin properly ignored. Found by mancha and Kasom Koht-arsa, #308 * Fix build error with configurations where ecdhe-psk is the only key exchange. Found and fix provided by Chris Hammond. #270 * Fix failures in mpi on sparc(64) due to use of bad assembly code. Found by Kurt Danielson. #292 * Fix typo in name of the extkeyusage oid. found by inestlerode, #314 * Fix bug in asn.1 encoding of booleans that caused generated ca certificates to be rejected by some applications, including OS X Keychain. Found and fixed by Jonathan Leroy, Inikup. * Fix 'destination buffer is too small' error in cert_write program. Found and fixed by Jonathan Leroy, Inikup. - Update to 1.3.14 * Added fix for CVE-2015-5291 (boo#949380) to prevent heap corruption due to buffer overflow of the hostname or session ticket. Found by Guido Vranken, Intelworks. * Fix stack buffer overflow in pkcs12 decryption (used by mbedtls_pk_parse_key(file)() when the password is 129 bytes. Found by Guido Vranken, Intelworks. Not triggerable remotely. * Fix potential buffer overflow in mbedtls_mpi_read_string(). Found by Guido Vranken, Intelworks. Not exploitable remotely in the context of TLS, but might be in other uses. On 32 bit machines, requires reading a string of close to or larger than 1GB to exploit on 64 bit machines, would require reading a string of close to or larger than 2^62 bytes. * Fix potential random memory allocation in mbedtls_pem_read_buffer() on crafted PEM input data. ...
