Descrição técnica

Asterisk is an open source private branch exchange and telephony toolkit. Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, an unbounded `memcpy` of `OGG/Speex` packet data in `format_ogg_speex` can cause a heap buffer overflow and crash Asterisk when reading a file containing corrupted Speex audio. The attacker must create the file and make it available to Asterisk either through sufficiently elevated privileges or by convincing an Asterisk administrator to make it available. Asterisk must also be configured to play that file. This issue is fixed in Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3.

CVE-2026-1236157.5 ALT

———imgproxy 3.3.0 before 4.0.17 contains an out-of-bounds heap read and write in the ICO loader's BMP header reconstruction (vips_foreign_load_ico_header in vips/icoload.c) when an ICO entry declares a tiny data size, causing unvalidated header fields to be read and written past the allocated buffer. Unauthenticated remote attackers can supply a crafted ICO image to corrupt adjacent heap chunk metadata, triggering a glibc abort that crashes the worker.11h CVE-2026-1236149.8 CRÍ

———imgproxy from 4.0.0 before 4.0.16 contains an integer overflow in the ICO loader that allows remote attackers to trigger a heap buffer overflow via a crafted data_size value. Attackers can submit a crafted ICO image whose data_size wraps the allocation in vips/icoload.c, corrupting heap memory to crash the process or achieve code execution.11h CVE-2026-12396610.0 CRÍ

——0A vulnerability was determined in Tenda AC19 16.03.10.07. Affected by this issue is the function saveParentControlInfo of the file /goform/saveParentControlInfo. This manipulation of the argument deviceId causes heap-based buffer overflow. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized.23h CVE-2026-104267—

——0Botan is a C++ cryptography library. From 2.7.0 until 3.13.0, Botan's Scrypt implementation on 32-bit platforms computes required memory with unchecked multiplication, allowing attacker-controlled Scrypt parameters to wrap the allocation size and create a buffer smaller than the algorithm subsequently writes. The issue affects systems that enable Scrypt and accept arbitrary parameters from a hostile source, including applications that decrypt attacker-supplied encrypted private keys. A triggering parameter set can cause approximately four gigabytes of Scrypt output to be written past the allocated heap buffer, immediately crashing the process and causing denial of service. Arbitrary code execution is not demonstrated and appears difficult, but cannot be excluded from the overwrite primitive. This issue is fixed in version 3.13.0.2d CVE-2026-823087.5 ALT
