Description

2009-01-12 12:05:12 UTC
This issue affects all versions of the boinc-client package, as shipped
with Fedora updates of 9, 10 and devel.
Please fix.
Relevant part of the code (lib/crypt.C):
228 int decrypt_public(R_RSA_PUBLIC_KEY& key, DATA_BLOCK& in, DATA_BLOCK& out) {
229 RSA* rp = RSA_new();
230 public_to_openssl(key, rp);
231 RSA_public_decrypt(in.len, in.data, out.data, rp, RSA_PKCS1_PADDING);
232 out.len = RSA_size(rp);
233 return 0;
234 }
boinc-client-6.4.5-2.20081217svn.fc10 has been submitted as an update for Fedora 10. http://admin.fedoraproject.org/updates/boinc-client-6.4.5-2.20081217svn.fc10 boinc-client-6.4.5-2.20081217svn.fc9 has been submitted as an update for Fedora 9. http://admin.fedoraproject.org/updates/boinc-client-6.4.5-2.20081217svn.fc9 Common Vulnerabilities and Exposures assigned an identifier CVE-2009-0126 to the following vulnerability: The decrypt_public function in lib/crypt.cpp in the client in Berkeley Open Infrastructure for Network Computing (BOINC) 6.2.14 and 6.4.5 does not check the return value from the OpenSSL RSA_public_decrypt function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077.
