TITLE:
Apple iPhone / iPod touch Multiple Vulnerabilities
SECUNIA ADVISORY ID:
SA36677
VERIFY ADVISORY:
http://secunia.com/advisories/36677/
DESCRIPTION:
Some vulnerabilities, security issues, and weaknesses have been
reported in Apple iPhone and iPod touch, which can be exploited by
malicious people with physical access to the device to bypass certain
security restrictions or disclose sensitive information, and by
malicious people to disclose sensitive information, conduct
cross-site scripting and spoofing attacks, cause a DoS (Denial of
Service), or to compromise a user's system.
1) An error in CoreAudio when processing sample size table entries
of AAC and MP3 files can be exploited to cause a heap-based buffer
overflow and potentially execute arbitrary code.
2) An error in Exchange Support exists due to the "Require Passcode"
setting not being affected by the "Maximum inactivity time lock"
setting. This may lead to a time window, regardless of the Maximum
inactivity time lock" setting, in which a person with physical access
to the device is able to use the Exchange services.
3) A security issue exists in MobileMail due to deleted mails being
accessible via Spotlight search. This can be exploited by malicious
people with physical access to the device to disclose potentially
sensitive information.
4) An unspecified error exists in the Recovery Mode command parsing.
This can be exploited by a person with physical access to a device to
cause a heap-based buffer overflow and e.g. gain access to a locked
device.
5) A NULL pointer dereference error within the handling of SMS
arrival notifications can be exploited to cause a service
interruption.
6) An error in the handling of passwords in UIKit can be exploited by
a person with physical access to a device to disclose a password.
7) Safari includes the user name and password in the "Referer"
header, which can lead to the exposure of sensitive information.
8) Two vulnerabilities in WebKit can be exploited by malicious people
to conduct cross-site scripting attacks or potentially compromise a
user's system.
For more information:
SA35758
9) A vulnerability in WebKit can be exploited by malicious people to
conduct spoofing attacks.
For more information see vulnerability #6 in:
SA36269
