  4. Caz real din comuna clejani jud giurgiu: nea iacob de vreo 70 de ani platea minori sa il futa in cur. Si s-a bucurat tare cand l-au condamnat pt pedofilie. Isi freca mainile ca ajunge la bulau. Pana la urma i-au scos copiii lui (la vreo 45 de ani) certificat de nebun si l-au bagat la balamuc sa scape de rusine. Doamne pazeste!

  6. Interesant. Multumesc de ajutor in numele lui. Si eu tot pe mate-info a XII a chiar ☺. M-ar interesa si pe mine cum sa scot dintr-o aplicatie human verification. Am stat toata ziua sa deslusez cum sa fac asta si degeaba.

  7. Foxit Reader CPDF_Parser::m_pCryptoHandler Use After Free PDF Format Background Encryption Dictionaries Vulnerability Details ASLR and DEP Bypass Environment Details Trigger Author PDF Format Background PDF is a file format used to represent documents. A pdf is made of multiple data objects Simple Primitive Objects Integer, Number, Boolean, Null Complex Objects Format Name [.*] Array (.*) String <<.*>> Dictionary <.*> Hex String /.* Name stream.*endstream Stream These objects define how a pdf looks and what it contains. Structures in pdf are present in 2 types of objects - Direct and Indirect. An indirect object start with Object number and Generation number followed by the actual object. Indirect Objects can be directly referenced in other objects as n m R where n and m are object and generation numbers respectively. Dictionary objects are basic building blocks for the document. There are some general dictionary objects which are needed to form of page or the document itself. Most important is the Root dictionary which defines links to all other Pages, Metadata, Names etc. each of which can be some other object. Stream objects contain the most binary data such as fonts, pictures or compressed/encrypted data. Encryption Dictionaries A PDF document can be encrypted to protect its contents from unauthorized access. Encryption applies to all strings and streams in the document's PDF file, with some exceptions such as the Encrypt dictionary itself. Encryption mostly applies to stream objects. Encryption is not applied to other object types such as integers and boolean values, which are used primarily to convey information about the document's structure rather than its contents. Encryption-related information shall be stored in a document’s encryption dictionary, which shall be the value of the "Encrypt" entry in the document’s trailer dictionary. Vulnerability Details CPDF_Parser::StartParse sets m_pCryptoHandler for indirect objects of a pdf which are encrypted. m_pCryptoHandler should be nulled out when CPDF_Parser::ReleaseEncryptHandler is completed. Instead CPDF_Parser::ReleaseEncryptHandler does not remove the reference to CryptoHandler in CPDF_Parser and is dangling. Later when the parser starts to parse the objects referenced in the Root dictionary, m_pCryptoHandler+8 is called to decrypt the data. A similar bug was patched in pdfium in commit 741c362fb75fd8acd2ed2059c6e3e716a63a7ac8. See https://bugs.chromium.org/p/chromium/issues/detail?id=726503 ASLR and DEP Bypass PDFs allow embedding JS in the document which can be executed automatically if entered in OpenAction of Catalog type dictionary. Once we have JS execution we can spray objects in the process space so that we get to a predictable address where we'll write our ROP chain. When a PDF document is signed in Foxit Reader, it uses plugins\jrsys\x86\jrsysMSCryptoDll.dll from the installation directory to read the signed information which loads jrsysCryptoDll.dll on a static address of 0x10000000. This dll imports VirtualAlloc which makes it easier to execute payload. The attached exploit uses heap spraying to get a predictable memory layout and uses a rop chain for allocating an RWX page, copying and executing the payload. Environment Details This exploit was tested using Foxit Reader 9.0.1.1049 x86 running on MS Windows 7 Enterprise Build 7601 SP1 x86. The exploit requires the heap to be in a specific state, if the exploit fails, please try again. Please refer to the video demo. This vulnerability is also present in Foxit PDF Reader and Converter for Android too. Trigger bitcoins.pdf is the crafted pdf that does the re-allocation of the freed memory and triggers the core bug. If you want to reproduce the crash in debugger, please enable Page Heaps for FoxitReader.exe and open bitcoins.pdf. Demo Author This crash was found by Cloudfuzz - A fuzzing platform developed at Payatu. Further analysis and exploitation was done by Sudhakar Sursa: https://github.com/payatu/CVE-2018-14442

  8. GG pentru initiativa. Vad ca ai ceva timp pe forumu' asta si eu intru din ce in ce mai rar. Am incercat sa dau c/p intr-uun IDE sa bag cateva imbunatatiri da' sa-mi bag pula daca nu mai mult m-am enervat. Daca vrei sa faci ceva cum trebe' pentru forum (chiar daca spui ca ii facut asa intr-o doara in conced), fa si tu un commit pe git sau ce folosesti tu, pune un link aici, alege o versiune de Python recenta nu ceva care o sa fie deprecated maine poimaine. Ca mai vine azi unu' cu un edit, maine altu' cu un issue, si pac te trezesti cu meleonu' de la Dragnea care iti cumpara aplicatia si o baga pe RATB. Pwp & no homo
