CVE-2003-0078 EXPLOIT

5.0
MEDIUM · CVSS 2.0 · EPSS 13.7% (pctl 96)

Patch early

A public exploit exists.

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."
