CVE-2009-4028
Publication date 30 November 2009
Last updated 24 July 2024
Ubuntu priority
The vio_verify_callback function in viosslfactories.c in MySQL 5.0.x before 5.0.88 and 5.1.x before 5.1.41, when OpenSSL is used, accepts a value of zero for the depth of X.509 certificates, which allows man-in-the-middle attackers to spoof arbitrary SSL-based MySQL servers via a crafted certificate, as demonstrated by a certificate presented by a server linked against the yaSSL library.

Notes

dapper doesn't build with ssl hardy+ builds with yaSSL none of our releases are vulnerable, as the yaSSL code ignores the verify callback (see mysql bug)
