Integer Overflow or Wraparound

In PHP versions 7.3.x below 7.3.29, 7.4.x below 7.4.21 and 8.0.x below 8.0.8, when using Firebird PDO driver extension, a malicious database server could cause crashes in various database functions, such as getAttribute(), execute(), fetch() and others by returning invalid response data that is not parsed correctly by the driver. This can result in crashes, denial of service or potentially memory corruption.Show less

In memory management driver, there is a possible memory corruption due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS05403499; Issue ID: ALPS05411456.Show less

Possible Integer overflow to buffer overflow issue can occur due to improper validation of input parameters when extscan hostlist configuration command is received in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer Electronics Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon IoT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon Wired Infrastructure and NetworkingShow less

An integer overflow exists in HAProxy 2.0 through 2.5 in htx_add_header that can be exploited to perform an HTTP request smuggling attack, allowing an attacker to bypass all configured http-request HAProxy ACLs and possibly other ACLs.Show less

An integer overflow was addressed with improved input validation. This issue is fixed in iOS 14.5.1 and iPadOS 14.5.1, tvOS 14.6, iOS 12.5.3, Safari 14.1.1, macOS Big Sur 11.3.1. Processing maliciously crafted web content may lead to arbitrary code execution.Show less

An integer overflow was addressed with improved input validation. This issue is fixed in macOS Big Sur 11.3, Security Update 2021-002 Catalina, Security Update 2021-003 Mojave. An attacker in a privileged network position may be able to leak sensitive user information.Show less

An integer overflow was addressed through improved input validation. This issue is fixed in iOS 14.7, macOS Big Sur 11.5, watchOS 7.6, tvOS 14.7, Security Update 2021-005 Mojave, Security Update 2021-004 Catalina. Processing a maliciously crafted font file may lead to arbitrary code execution.Show less

Amazon Kindle e-reader prior to and including version 5.13.4 contains an Integer Overflow that leads to a Heap-Based Buffer Overflow in function CJBig2Image::expand() and results in a memory corruption that leads to code execution when parsing a crafted PDF book.Show less

XMP Toolkit SDK version 2020.1 (and earlier) is affected by an Integer Overflow vulnerability potentially resulting in application-level denial of service in the context of the current user. Exploitation requires user interaction in that a victim must open a crafted file.Show less

Tizen RT RTOS version 3.0.GBB is vulnerable to integer wrap-around in functions_calloc and mm_zalloc. This improper memory assignment can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crashShow less

An exploitable integer overflow vulnerability exists within the MPEG-4 decoding functionality of the GPAC Project on Advanced Content library v1.0.1. A specially crafted MPEG-4 input can cause an integer overflow when the library encounters an atom using the “trun” FOURCC code due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. An attacker can convince a user to open a video to trigger this vulnerability.Show less
