Security Fix(es):
opensc: A vulnerability was found in OpenSC where PKCS#1 encryption padding removal is not implemented as side-channel resistant. This issue may result in the potential leak of private data.(CVE-2023-5992)
opensc: A flaw was found in OpenSC packages that allow a potential PIN bypass. When a token/card is authenticated by one process, it can perform cryptographic operations in other processes when an empty zero-length pin is passed. This issue poses a security risk, particularly for OS logon/screen unlock and for small, permanently connected tokens to computers. Additionally, the token can internally track login status. This flaw allows an attacker to gain unauthorized access, carry out malicious actions, or compromise the system without the user's awareness.(CVE-2023-40660)
opensc: Several memory vulnerabilities were identified within the OpenSC packages, particularly in the card enrollment process using pkcs15-init when a user or administrator enrolls cards. To take advantage of these flaws, an attacker must have physical access to the computer system and employ a custom-crafted USB device or smart card to manipulate responses to APDUs. This manipulation can potentially allow compromise key generation, certificate loading, and other card management operations during enrollment.(CVE-2023-40661)
opensc: A vulnerability was found in OpenSC. This issue causes a buffer overrun in the pkcs15 cardos_have_verifyrc_package. This flaw allows an attacker to supply a smart card package with a malformed ASN1 context. The cardos_have_verifyrc_package function scans the ASN1 buffer for two tags, where the remaining length is wrongly calculated due to a moved starting pointer, leading to a possible heap-based buffer out-of-bounds read. In cases where ASN is enabled while compiling, this problem causes a crash, and further information leaks or more damage is likely.(CVE-2023-2977)
opensc: An out-of-bounds read vulnerability was found in OpenSC packages within the MyEID driver when handling symmetric key encryption. Exploiting this flaw requires an attacker to have physical access to the computer and a specially crafted USB device or smart card. This flaw allows the attacker to manipulate APDU responses and potentially gain unauthorized access to sensitive data, compromising the system's security.(CVE-2023-4535)
opensc: bugfix
poppler: An out-of-bounds read exists within Poppler's JBIG2Bitmap::combine function in JBIG2Stream.cc. This flaw allows an attacker to crash the application via a carefully crafted pdf file. This issue can be triggered through the pdfimages utility.(CVE-2024-56378)
poppler: A flaw was found in Poppler that allows a remote attacker to cause a Denial of Service (DoS) via a crafted PDF file in OutlineItem::open.(CVE-2023-34872)
poppler: A flaw was found in the Poppler's Pdfinfo utility. This issue occurs when using -dests parameter with pdfinfo utility. By using certain malformed input files, an attacker could cause the utility to crash, leading to a denial of service.(CVE-2024-6239)
poppler: bugfix
