Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

In the Linux kernel, the following vulnerability has been resolved: PM / devfreq: Fix buffer overflow in trans_stat_show Fix buffer overflow in trans_stat_show(). Convert simple snprintf to the more secure scnprintf with size of PAGE_SIZE. Add condition checking if we are exceeding PAGE_SIZE and exit early from loop. Also add at the end a warning that we exceeded PAGE_SIZE and that stats is disabled. Return -EFBIG in the case where we don't have enough space to write the full transition table. Also document in the ABI that this function can return -EFBIG error.Show less

In the Linux kernel, the following vulnerability has been resolved: crypto: scomp - fix req->dst buffer overflow The req->dst buffer size should be checked before copying from the scomp_scratch->dst to avoid req->dst buffer overflow problem.Show less

In TP-Link Omada er605 1.0.1 through (v2.6) 2.2.3, a cloud-brd binary is susceptible to an integer overflow that leads to a heap-based buffer overflow. After heap shaping, an attacker can achieve code execution in the context of the cloud-brd binary that runs at the root level. This is fixed in ER605(UN)_v2_2.2.4 Build 020240119.Show less

An unautheticated remote attacker could send specifically crafted packets to a affected device. If an authenticated user then views that data in a specific page of the web-based management a buffer overflow will be triggered to gain full access of the device.Show less

A vulnerability has been identified in Cerberus PRO EN Engineering Tool (All versions < IP8), Cerberus PRO EN Fire Panel FC72x IP6 (All versions < IP6 SR3), Cerberus PRO EN Fire Panel FC72x IP7 (All versions < IP7 SR5), Cerberus PRO EN X200 Cloud Distribution IP7 (All versions < V3.0.6602), Cerberus PRO EN X200 Cloud Distribution IP8 (All versions < V4.0.5016), Cerberus PRO EN X300 Cloud Distribution IP7 (All versions < V3.2.6601), Cerberus PRO EN X300 Cloud Distribution IP8 (All versions < V4.2.5015), Cerberus PRO UL Compact Panel FC922/924 (All versions < MP4), Cerberus PRO UL Engineering Tool (All versions < MP4), Cerberus PRO UL X300 Cloud Distribution (All versions < V4.3.0001), Desigo Fire Safety UL Compact Panel FC2025/2050 (All versions < MP4), Desigo Fire Safety UL Engineering Tool (All versions < MP4), Desigo Fire Safety UL X300 Cloud Distribution (All versions < V4.3.0001), Sinteso FS20 EN Engineering Tool (All versions < MP8), Sinteso FS20 EN Fire Panel FC20 MP6 (All versions < MP6 SR3), Sinteso FS20 EN Fire Panel FC20 MP7 (All versions < MP7 SR5), Sinteso FS20 EN X200 Cloud Distribution MP7 (All versions < V3.0.6602), Sinteso FS20 EN X200 Cloud Distribution MP8 (All versions < V4.0.5016), Sinteso FS20 EN X300 Cloud Distribution MP7 (All versions < V3.2.6601), Sinteso FS20 EN X300 Cloud Distribution MP8 (All versions < V4.2.5015), Sinteso Mobile (All versions < V3.0.0). The network communication library in affected systems does not validate the length of certain X.509 certificate attributes which might result in a stack-based buffer overflow. This could allow an unauthenticated remote attacker to execute code on the underlying operating system with root privileges.Show less

In sendHciCommand of bluetooth_hci.cc, there is a possible out of bounds read due to a heap buffer overflow. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation.Show less

In dumpBatteryDefend of dump_power.cpp, there is a possible out of bounds read due to a heap buffer overflow. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.Show less

A vulnerability was found in SourceCodester Tourist Reservation System 1.0. It has been declared as critical. This vulnerability affects the function ad_writedata of the file System.cpp. The manipulation of the argument ad_code leads to buffer overflow. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. VDB-256282 is the identifier assigned to this vulnerability.Show less

A buffer overflow issue was addressed with improved memory handling. This issue is fixed in iOS 16.7.6 and iPadOS 16.7.6, iOS 17.4 and iPadOS 17.4, macOS Monterey 12.7.4, macOS Sonoma 14.4, macOS Ventura 13.6.5, tvOS 17.4, visionOS 1.1, watchOS 10.4. Processing an image may lead to arbitrary code execution.Show less

In the Linux kernel, the following vulnerability has been resolved: NFSD: Fix READDIR buffer overflow If a client sends a READDIR count argument that is too small (say, zero), then the buffer size calculation in the new init_dirlist helper functions results in an underflow, allowing the XDR stream functions to write beyond the actual buffer. This calculation has always been suspect. NFSD has never sanity- checked the READDIR count argument, but the old entry encoders managed the problem correctly. With the commits below, entry encoding changed, exposing the underflow to the pointer arithmetic in xdr_reserve_space(). Modern NFS clients attempt to retrieve as much data as possible for each READDIR request. Also, we have no unit tests that exercise the behavior of READDIR at the lower bound of @count values. Thus this case was missed during testing.Show less

Dell Digital Delivery, versions prior to 5.2.0.0, contain a Buffer Overflow Vulnerability. A local low privileged attacker could potentially exploit this vulnerability, leading to arbitrary code execution and/or privilege escalation.Show less

LBT T300-T390 v2.2.1.8 were discovered to contain a stack overflow via the ApCliSsid parameter in the updateCurAPlist function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted POST request.Show less

A vulnerability with the handling of MPLS traffic for Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause the netstack process to unexpectedly restart, which could cause the device to stop processing network traffic or to reload. This vulnerability is due to lack of proper error checking when processing an ingress MPLS frame. An attacker could exploit this vulnerability by sending a crafted IPv6 packet that is encapsulated within an MPLS frame to an MPLS-enabled interface of the targeted device. A successful exploit could allow the attacker to cause a denial of service (DoS) condition. Note: The IPv6 packet can be generated multiple hops away from the targeted device and then encapsulated within MPLS. The DoS condition may occur when the NX-OS device processes the packet.Show less
