Hi guys,
I'm not very sure this is the right place to start this topic, but apparently there's been a new PolarSSL CVE that permits execution of malicious code. "PolarSSL versions starting with 1.0 and up to the PolarSSL 1.3.9 and PolarSSL 1.2.12 are affected by a remote attack in some configurations."
The fix is a one-line addition to asn1parse.c:

return( POLARSSL_ERR_ASN1_MALLOC_FAILED );

+
cur = cur->next;
}
}
========================================================
According to downloads.openwrt.org, the current version of the PolarSSL library is version 1.3.8, if I'm not mistaking (http://downloads.openwrt.org/barrier_br … ar71xx.ipk). So my question is basically, can this library be updated please?
