CImg Library Input Validation Error Vulnerability

CImg Library is an open source C++ library for image processing organized by DavidTschumperlé GREYC Davidtschumperlé Greyc. CImg Library suffers from an input validation error vulnerability that stems from the use of an insecure pattern for calculating the required heap buffer allocation size,...

grub2: Integer overflow in grub_ext2_read_link leads to heap-based buffer overflow

A flaw was found in grub2 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32MAX causes an arithmetic overflow, leading to a zero-sized memory allocation with a subsequent heap-based buffer overflow. The highest threat from this...

FreeBSD : FreeBSD -- posix_spawnp(3) buffer overflow (f8b46415-c264-11ea-8659-901b0ef719ab)

posixspawnp spawns a new thread with a limited stack allocated on the heap before delegating to execvp for the final execution within that thread. execvp would previously make unbounded allocations on the stack, directly proportional to the length of the user-controlled PATH environment variable...

Updated exiv2 packages fix security vulnerability

The updated packages fix a security vulnerability: A WebPImage::decodeChunks integer overflow in Exiv2 through 0.27.1 allows an attacker to cause a denial of service large heap allocation followed by a very long running loop via a crafted WEBP image file. CVE-2019-13111...

Heap overflow

An exploitable heap out-of-bounds write vulnerability exists in the TIF-parsing functionality of LEADTOOLS 20. A specially crafted TIF image can cause an offset beyond the bounds of a heap allocation to be written, potentially resulting in code execution. An attacker can specially craft a TIF ima...

CVE-2018-12121

Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Denial of Service with large HTTP headers: By using a combination of many requests with maximum sized headers almost 80 KB per connection, and carefully timed completion of the headers, it is possible to cause the HTTP...

CVE-2002-2439

operator new sometimes returns pointers to heap blocks which are too small. When a new array is allocated, the C++ run-time has to calculate its size. The product may exceed the maximum value which can be stored in a machine register. This error is ignored, and the truncated value is used for the...

CVE-2017-1000254

libcurl may read outside of a heap allocated buffer when doing FTP. When libcurl connects to an FTP server and successfully logs in anonymous or not, it asks the server for the current directory with the PWD command. The server then responds with a 257 response containing the path, inside double...
