What is CVE-2003-0078?
CVE-2003-0078 is a medium-severity vulnerability in Freebsd Freebsd, published on 1 Sep 2004. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
ssl3_get_record in s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before 0.9.6i does not perform a MAC computation if an incorrect block cipher padding is used, which causes an information leak (timing discrepancy) that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading to extraction of the original plaintext, aka the "Vaudenay timing attack."
Weakness: CWE-203
