Bugzilla 3.2 before 3.2 RC2, 3.0 before 3.0.6, 2.22 before 2.22.6, 2.20 before 2.20.7, and other versions after 2.17.4 allows remote authenticated users to bypass moderation to approve and disapprove quips via a direct request to quips.cgi with the action parameter set to "approve."

email_in.pl in Bugzilla 2.23.4, 3.0.x before 3.0.4, and 3.1.x before 3.1.4 allows remote authenticated users to more easily spoof the changer of a bug via a @reporter command in the body of an e-mail message, which overrides the e-mail address as normally obtained from the From e-mail header. NOTE: since From headers are easily spoofed, this only crosses privilege boundaries in environments that provide additional verification of e-mail addresses.

The offer_account_by_email function in User.pm in the WebService for Bugzilla before 3.0.2, and 3.1.x before 3.1.2, does not check the value of the createemailregexp parameter, which allows remote attackers to bypass intended restrictions on account creation.

Buffer overflow in LHA allows remote attackers to execute arbitrary code via long pathnames in LHarc format 2 headers for a .LHZ archive, as originally demonstrated using the "x" option but also exploitable through "l" and "v", and fixed in header.c, a different issue than CVE-2004-0771.
