Mozilla products fail to properly handle malformed VCard attachments, which allows a buffer overflow to occur. This vulnerability may allow a remote attacker to execute arbitrary code on a vulnerable system.
According to Mozilla Foundation Security Advisory 2006-49:
_A VCard attachment with a malformed base64 field (such as a photo) can trigger a heap buffer overwrite. _These have proven exploitable in the past, though in this case the overwrite is accompanied by an integer underflow that would attempt to copy more data than the typical machine has, leading to a crash.
For more information and a complete list of affected products, refer to Mozilla Foundation Security Advisory 2006-49.
A remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. The attacker could also cause the vulnerable application to crash.
