I've updated the version of OpenSSL to 1.0.1a-1. I also updated the 0.9.8 libs to 0.9.8v-1.
This is an upstream security release. The Cygwin release is build from the vanilla sources. Here's the official security advisory: ------------------------------------------------------------------------ OpenSSL Security Advisory [19 Apr 2012] ======================================= ASN1 BIO vulnerability (CVE-2012-2110) ======================================= A potentially exploitable vulnerability has been discovered in the OpenSSL function asn1_d2i_read_bio. Any application which uses BIO or FILE based functions to read untrusted DER format data is vulnerable. Affected functions are of the form d2i_*_bio or d2i_*_fp, for example d2i_X509_bio or d2i_PKCS12_fp. Applications using the memory based ASN1 functions (d2i_X509, d2i_PKCS12 etc) are not affected. In particular the SSL/TLS code of OpenSSL is *not* affected. Applications only using the PEM routines are not affected. S/MIME or CMS applications using the built in MIME parser SMIME_read_PKCS7 or SMIME_read_CMS *are* affected. The OpenSSL command line utility is also affected if used to process untrusted data in DER format. Note: although an application using the SSL/TLS portions of OpenSSL is not automatically affected it might still call a function such as d2i_X509_bio on untrusted data and be vulnerable. Thanks to Tavis Ormandy, Google Security Team, for discovering this issue and to Adam Langley <a...@chromium.org> for fixing it. Affected users should upgrade to OpenSSL 1.0.1a, 1.0.0i or 0.9.8v.
