CWE-682

Incorrect verifier pruning in BPF in Linux Kernel >=5.4 leads to unsafe code paths being incorrectly marked as safe, resulting in arbitrary read/write in kernel memory, lateral privilege escalation, and container escape.

Podatność w komponencie oneflow.permute biblioteki OneFlow v0.9.1 powoduje nieprawidłowe obliczenia podczas wykonywania operacji na tej samej wymiarze. Błąd sklasyfikowany jako krytyczny może prowadzić do nieoczekiwanych i nieprawidłowych wyników obliczeń w środowiskach przetwarzania danych.

A flaw was found in moodle where logic used to count failed login attempts could result in the account lockout threshold being bypassed.

A stack-based buffer overflow in handle_request function in DHT.c in toxcore 0.1.9 through 0.1.11 and 0.2.0 through 0.2.12 (caused by an improper length calculation during the handling of received network packets) allows remote attackers to crash the process or potentially execute arbitrary code via a network packet.

Airbrush FW's scratch memory allocator is susceptible to numeric overflow. When the overflow occurs, the next allocation could potentially return a pointer within the previous allocation's memory, which could lead to improper memory access.Product: AndroidVersions: Android kernelAndroid ID: A-135772851

A Security Feature Bypass vulnerability exists in MSR JavaScript Cryptography Library that is caused by incorrect arithmetic computations, aka "MSR JavaScript Cryptography Library Security Feature Bypass Vulnerability." This affects Microsoft Research JavaScript Cryptography Library.

Podatność typu wrap-around error w sterowniku trybu jądra Linux dla kontrolerów Intel Ethernet umożliwia uwierzytelnionemu użytkownikowi lokalnemu eskalację uprawnień. Ocena CVSS 9.3 (Critical) wskazuje na poważne ryzyko dla systemów Linux z podatnym sterownikiem.

Podatność w węźle Zcash Zebra (napisanym w Rust) powoduje nieprawidłowe zliczanie operacji podpisów (sigops) w blokach, co umożliwia akceptację bloków odrzucanych przez referencyjny węzeł zcashd. Skutkuje to możliwością trwałego podziału sieci (network split) między węzłami Zebra a węzłami zcashd.

In Solana rBPF versions 0.2.26 and 0.2.27 are affected by Incorrect Calculation which is caused by improper implementation of sdiv instruction. This can lead to the wrong execution path, resulting in huge loss in specific cases. For example, the result of a sdiv instruction may decide whether to transfer tokens or not. The vulnerability affects both integrity and may cause serious availability problems.

Internet Connection Sharing (ICS) Remote Code Execution Vulnerability

STB v2.27 was discovered to contain an integer shift of invalid size in the component stbi__jpeg_decode_block_prog_ac.

In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).

In reassemble_and_dispatch of packet_fragmenter.cc, there is possible out of bounds write due to an incorrect bounds calculation. This could lead to remote code execution over Bluetooth with no additional execution privileges needed.

An issue was discovered in Xen through 4.12.x allowing x86 PV guest OS users to cause a denial of service via degenerate chains of linear pagetables, because of an incorrect fix for CVE-2017-15595. "Linear pagetables" is a technique which involves either pointing a pagetable at itself, or to another pagetable of the same or higher level. Xen has limited support for linear pagetables: A page may either point to itself, or point to another pagetable of the same level (i.e., L2 to L2, L3 to L3, and so on). XSA-240 introduced an additional restriction that limited the "depth" of such chains by allowing pages to either *point to* other pages of the same level, or *be pointed to* by other pages of the same level, but not both. To implement this, we keep track of the number of outstanding times a page points to or is pointed to another page table, to prevent both from happening at the same time. Unfortunately, the original commit introducing this reset this count when resuming validation of a partially-validated pagetable, incorrectly dropping some "linear_pt_entry" counts. If an attacker could engineer such a situation to occur, they might be able to make loops or other arbitrary chains of linear pagetables, as described in XSA-240. A malicious or buggy PV guest may cause the hypervisor to crash, resulting in Denial of Service (DoS) affecting the entire host. Privilege escalation and information leaks cannot be excluded. All versions of Xen are vulnerable. Only x86 systems are affected. Arm systems are not affected. Only x86 PV guests can leverage the vulnerability. x86 HVM and PVH guests cannot leverage the vulnerability. Only systems which have enabled linear pagetables are vulnerable. Systems which have disabled linear pagetables, either by selecting CONFIG_PV_LINEAR_PT=n when building the hypervisor, or adding pv-linear-pt=false on the command-line, are not vulnerable.

Inappropriate implementation in JavaScript in Google Chrome prior to 76.0.3809.87 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

ngiflib 0.4 has a heap-based buffer overflow in WritePixel() in ngiflib.c when called from DecodeGifImg, because deinterlacing for small pictures is mishandled.

A remote code execution vulnerability in the Android media framework (libmpeg2). Product: Android. Versions: 6.0, 6.0.1, 7.0, 7.1.1, 7.1.2, 8.0. Android ID A-63874456.

The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation.

Xen allows local OS guest users to cause a denial of service (crash) or possibly obtain sensitive information or gain privileges via vectors involving transitive grants.
