Detection & IOCsextracted from sources · hover to see the quote
- →The vulnerability is triggered inside JBIG2Stream::readTextRegionSeg in CoreGraphics.framework; monitor for crashes or anomalous execution originating from this function. ↗
- →Exploit delivery is via iMessage attachment parsing (zero-click); look for iMessage processes spawning unexpected child processes or crashing while parsing attachments. ↗
- →A dyld_shared_cache slide of 0 in crash logs indicates all system modules loaded at fixed addresses, which is a sign of exploit-induced ASLR bypass; flag crash logs exhibiting this condition. ↗
- →Exploitation replaces the virtual function table of JBIG2Segment objects and bypasses PAC; forensic analysis of crash logs should check for vtable corruption on JBIG2Segment objects. ↗
- →The exploit is triggered by processing a maliciously crafted PDF (or JBIG2-encoded iMessage attachment); inspect incoming iMessage attachments and PDF files for embedded JBIG2 streams with oversized symbol dictionary segment sizes that cause integer overflow in numSyms. ↗
- ·The crash address 0x181d6e228 is not the initial exploitation point; it is a downstream crash after vtable hijacking has already occurred, so using it alone as a detection anchor may miss earlier exploitation stages. ↗
- ·The ForcedEntry exploit was observed bypassing BlastDoor, Apple's iMessage sandboxing defense; BlastDoor alone should not be relied upon as a mitigating control for this CVE on unpatched devices. ↗

CVE-2022-38784 [HIGH] CWE-190 poppler: integer overflow in JBIG2 decoder using malformed files
poppler: integer overflow in JBIG2 decoder using malformed files
Poppler prior to and including 22.08.0 contains an integer overflow in the JBIG2 decoder (JBIG2Stream::readTextRegionSeg() in JBIGStream.cc). Processing a specially crafted PDF file or JBIG2 image could lead to a crash or the execution of arbitrary code. This is similar to the vulnerability described by CVE-2022-38171 in Xpdf.
An integer overflow issue was discovered in Popplers' JBIG2 decoder in the JBIG2Stream::readTextRegionSeg() function in JBIGStream.cc file. This flaw allows an attacker to trick a user into opening a malformed PDF file or JBIG2 image in the application, triggering an integer overflow, which could result in a crash or may lead to the execution of arbitrary code on the target system.

Posted by Maddie Stone, Google Project Zero
This is our third annual year in review of 0-days exploited in-the-wild [2020, 2019]. Each year we’ve looked back at all of the detected and disclosed in-the-wild 0-days as a group and synthesized what we think the trends and takeaways are. The goal of this report is not to detail each individual exploit, but instead to analyze the exploits from the year as a group, looking for trends, gaps, lessons learned, successes, etc. If you’re interested in the analysis of individual exploits, please check out our root cause analysis repository.

Posted by Ian Beer & Samuel Groß of Google Project Zero
We want to thank Citizen Lab for sharing a sample of the FORCEDENTRY exploit with us, and Apple’s Security Engineering and Architecture (SEAR) group for collaborating with us on the technical analysis. The editorial opinions reflected below are solely Project Zero’s and do not necessarily reflect those of the organizations we collaborated with during this research.
Earlier this year, Citizen Lab managed to capture an NSO iMessage-based zero-click exploit being used to target a Saudi activist. In this two-part blog post series we will describe for the first time how an in-the-wild zero-click iMessage exploit works.
Based on our research and findings, we assess this to be one of the most technically sophisticated exploits

SentinelOne’s Cybersecurity Predictions 2022: What’s Next?
2021 was a year in which everything escalated . The pandemic triggered separation, isolation, and general unease in our ability to discern the good from the bad. In cybersecurity, we saw a sharp increase in the number of threat actors riding the wave of the ransomware economy, more governments using cyberspace to influence nation-state politics, and more software vulnerabilities. The combined effect of these has made breaches easier and security harder.
So where will 2022 lead us? Our predictions last year weren’t far off the mark, so as we look forward to another year in the trenches of cybersecurity, we gather some of SentinelOne’s best researchers and thought leaders once again to read the tea leaves of the central motifs they see coming to bear in 2022.

Citizen Lab has released a report detailing sophisticated iPhone exploits being used against nine Bahraini activists. The activists were reportedly hacked with the NSO Group’s Pegasus spyware using two zero-click iMessage exploits: Kismet , which was identified in 2020; and ForcedEntry , a new vulnerability that was identified in 2021. Zero-click attacks are labeled as sophisticated threats because unlike t

[MEDIUM] Microsoft Patch Tuesday, September 2021 Edition
Microsoft today pushed software updates to plug dozens of security holes in Windows and related products, including a vulnerability that is already being exploited in active attacks. Also, Apple has issued an emergency update to fix a flaw that’s reportedly been abused to install spyware on iOS products, and Google‘s got a new version of Chrome that tackles two zero-day flaws. Finally, Adobe has released critical security updates for Acrobat, Reader and a slew of other software.
Four of the flaws fixed in this patch batch earned Microsoft’s most-dire “critical” rating, meaning they could be exploited by miscreants or malware to remotely compromise a Windows PC with little or no help from the user.
Top of the critical heap is CVE-2021-40444, which affects the “MSHTML” component of Interne

Improper Input Validation

CWE-20 Improper Input Validation
CWE-20: Improper Input Validation
The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly.
Input validation is a frequently-used technique
for checking potentially dangerous inputs in order to
ensure that the inputs are safe for processing within the
code, or when communicating with other components. Input can consist of: raw data - strings, numbers, parameters, file contents, etc. metadata - information about the raw data, such as headers or size Data can be simple or structured. Structured data
can be composed of many nested layers, composed of
combinations of metadata and raw data, with other simple or
structured data. Many properties of raw data or metadata may n
CWE
Integer Overflow or Wraparound
mitre_cwe
CWE-190 Integer Overflow or Wraparound
CWE-190: Integer Overflow or Wraparound
The product performs a calculation that can
produce an integer overflow or wraparound when the logic
assumes that the resulting value will always be larger than
the original value. This occurs when an integer value is
incremented to a value that is too large to store in the
associated representation. When this occurs, the value may
become a very small or negative number.

Note: This weakness may become security critical when determining the offset or size in behaviors such as memory allocation, copying, and concatenation.
Common Consequences:
Scope: Availability. Impact: DoS: Crash, Exit, or Restart, DoS: Resource Consumption (Memory), DoS: Instability. This weakness can generally lead to undefined behav
