CVSS
ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer.

CVE-2011-0762
Exploit Found
The vsf_filename_passes_filter function in ls.c in vsftpd before 2.3.3 allows remote authenticated users to cause a denial of service (CPU consumption and process slot exhaustion) via crafted glob expressions in STAT commands in multiple FTP sessions, a different vulnerability than CVE-2010-2632.
Severity: MEDIUM
7.1
CVSS
Memory leak in a certain Red Hat deployment of vsftpd before 2.0.5 on Red Hat Enterprise Linux (RHEL) 3 and 4, when PAM is used, allows remote attackers to cause a denial of service (memory consumption) via a large number of invalid authentication attempts within the same session, a different vulnerability than CVE-2007-5962.
Severity: HIGH
5.0
CVSS
vsftpd before 1.2.2, when under heavy load, allows attackers to cause a denial of service (crash) via a SIGCHLD signal during a malloc or free call, which is not re-entrant.
Severity: MEDIUM
5.0
CVSS
vsftpd 1.1.3 generates different error messages depending on whether or not a valid username exists, which allows remote attackers to identify valid usernames.
