Certificate validation vulnerability in Git

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

There seems to be a security issue in the way git uses openssl for
certificate validation. Similar occurrences have been found and
documented in other open source projects, the research can be found at
[1].

-=========]
- imap-send.c

Line 307

 307   ret = SSL_connect(sock->ssl);
 308   if (ret <= 0) {
 309     socket_perror("SSL_connect", sock, ret);
 310     return -1;
 311   }
 312

Certificate validation errors are signaled either through return
values of SSL_connect or by setting internal flags. The internal flags
need to be checked using the SSL_get_verify_result function. This is
not performed.

Kindly fix these issues, file a CVE and credit it to Dhanesh K. and
Zubin Mithra. Thanks.

Hope this helps.

Thanks!
