Software installed and run as a non-privileged user may conduct GPU system calls to trigger an integer overflow and allow OOB writes to GPU buffers. The integer overflow caused when mapping a GPU buffer >4GB causes corruption of array length, and can lead to kernel panics or out of bounds access.

Software installed and run as a non-privileged user may conduct improper GPU system calls to the execution of an error path that triggers an OOB read & write. An error can be triggered which causes the index of the array element to be cleaned up by the error path would be outside of the array…

Memory overflow in WebAuth authentication can lead to unpredictable or erroneous behavior or Denial of Service in Citrix NetScaler ADC and Citrix NetScaler Gateway.

A flaw has been found in Cairo-dock Glx-Dock 3.4.0. The affected element is an unknown function of the file bg_forum.php of the component href Attribute Handler. This manipulation of the argument f causes cross site scripting. The attack may be initiated remotely. The exploit has been published…

Memory overflow in RTSP ALG can lead to unpredictable or erroneous behavior or Denial of Service in Citrix NetScaler

Multiple Memory overflow vulnerabilities can lead to unpredictable or erroneous behavior and Denial of Service in Citrix NetScaler ADC and Citrix NetScaler Gateway.

Memory overflow in SAML authentication can lead to unpredictable or erroneous behavior or Denial of Service in Citrix NetScaler ADC and Citrix NetScaler Gateway.

boot_save_boot_status() in boot/bootutil/src/boot_record.c reads the image's EXPECTED_HASH_TLV into a stack buffer image_hash[IMAGE_HASH_SIZE] that is never zero-initialised. The TLV handler validates only the upper bound (len > sizeof(image_hash)) and then reads exactly len bytes, so a TLV…

MCUboot's Zephyr serial-recovery upload handler bs_upload() in boot/boot_serial/src/boot_serial.c decodes the host-supplied image field of an MCUmgr image-upload request into img_num (a full 32-bit value) and latches it on the off == 0 packet without any range check. It then passes img_num…

split_image_check() in boot/bootutil/src/loader.c declares a fixed uint8_t loader_hash[32] buffer and passes it as the out_hash out-parameter to bootutil_img_validate(). That routine copies IMAGE_HASH_SIZE bytes into out_hash (memcpy(out_hash, hash, IMAGE_HASH_SIZE) in…

In MCUboot's serial-recovery encrypted-image support (boot/boot_serial/src/boot_serial_encryption.c), decrypt_image_inplace() and boot_image_validate_encrypted() each keep a stack-local struct boot_status. boot_enc_load() writes the plaintext per-image AES key into its enckey[] field. Neither…

When MCUboot is built with the TinyCrypt crypto backend (MCUBOOT_USE_TINYCRYPT), bootutil_aes_ctr_drop() in boot/bootutil/include/bootutil/crypto/aes_ctr_tinycrypt.h was an empty stub. The AES-CTR context for this backend is the fully expanded AES-128 key schedule (struct tc_aes_key_sched_struct).…

Tight JPEG decoding in TightVNC and UltraVNC viewers contains a heap-based buffer overflow because an attacker-controlled framebuffer rectangle width is not validated against a fixed-size decoding buffer. A malicious VNC server can cause an out-of-bounds heap write when a user connects, resulting…

Software installed and run as a non-privileged user may conduct improper GPU system calls through the DDK kernel module interface. Under unsupported use of the interface, a use-after-free condition may occur that can lead to kernel memory corruption, platform instability, or system reboot. The…

MCUboot's serial-recovery image-upload handler bs_upload() in boot/boot_serial/src/boot_serial.c declares const struct flash_area *fap = NULL and assigns it only via flash_area_open() part-way through the function. Two early validation failures (goto out_invalid_data) — a CBOR map that fails to…

A vulnerability was found in lanyulei ferry 1.0.0-beta.1/1.0.0. Affected is an unknown function of the file middleware/auth.go of the component JWT Validation. The manipulation results in improper authentication. The attack can be executed remotely. The exploit has been made public and could be…

A vulnerability was determined in SourceCodester Smart Attendance System with QR Code Scanner 1.0. Affected by this vulnerability is an unknown functionality of the file reset_password.php. This manipulation of the argument Username causes cross site scripting. The attack is possible to be carried…

A vulnerability was identified in SourceCodester Food Ordering System 1.0. Affected by this issue is some unknown functionality of the file admin/update_food.php of the component Admin Image Handler. Such manipulation of the argument cmd leads to unrestricted upload. The attack may be performed…

A security flaw has been discovered in SourceCodester Food Ordering System 1.0. This affects an unknown part of the file admin/add_category.php of the component Admin Write Handler. Performing a manipulation of the argument title/description/price/current_image/featured/active/id results in sql…

The MCUboot TLV iterator bootutil_tlv_iter_next() in boot/bootutil/src/tlv.c walks image trailer TLVs with a single loop guard (it->tlv_off < it->tlv_end) and advances by sizeof(struct image_tlv) + tlv.it_len using the attacker-controlled it_len field, without validating that the entry's header or…

bootutil_img_hash() computes the image digest over ih_hdr_size + ih_img_size + ih_protect_tlv_size bytes, all three taken from the candidate image's header, and reads that span out of the slot without checking that it fits in the flash area. The three sizes are also summed without an overflow…

A vulnerability was identified in Linksys EA8100 1.0.3.216940. Impacted is an unknown function of the component Web UI. Such manipulation leads to cookie without 'httponly' flag. It is possible to launch the attack remotely. This attack is characterized by high complexity. The exploitability is…

A security flaw has been discovered in Linksys EA8100 1.0.3.216940. The affected element is an unknown function of the file etc/init.d/service_smbd.sh of the component SMB Service. Performing a manipulation of the argument ANON_ACCESS results in improper initialization. The attack can be initiated…

A weakness has been identified in AIP-PUB ACPs-community up to 2.2.0. The impacted element is the function send_verification_code of the file registry-server/app/account/service_auth.py of the component verify-code Endpoint. Executing a manipulation of the argument phone can lead to improper…

A vulnerability was detected in AIP-PUB ACPs-community up to 2.2.0. This impacts an unknown function of the file discovery-server/app/main.py of the component Discovery Server. The manipulation results in missing authentication. The attack may be launched remotely. The exploit is now public and…
