Multiple vendor S/MIME protocol implementation ASN.1 buffer overflow
| smime-asn1-bo (13603) |  High Risk |
Description:
Multiple vendor S/MIME (Secure/Multipurpose Internet Mail Extensions) protocol implementations are vulnerable to a buffer overflow. A remote attacker could send a malformed ASN.1 element to overflow a buffer and possibly execute arbitrary code on the system or cause a denial of service.
Consequences:
Gain Access
Remedy:
For Mandrake Linux 9.2:
Upgrade to the latest mozilla package (1.4-13.2.92mdk or later), as listed in MandrakeSoft Security Advisory MDKSA-2004:021 : mozilla . See References.
For Red Hat Linux 9:
Upgrade to the latest mozilla package (1.4.2-0.9.0 or later), as listed in RHSA-2004:112-09. See References.
