Improper Restriction of Operations within the Bounds of a Memory Buffer

The ReadSUNImage function in coders/sun.c in GraphicsMagick 1.3.26 has an issue where memory allocation is excessive because it depends only on a length field in a header. This may lead to remote denial of service in the MagickMalloc function in magick/memory.c.Show less

A size-validation issue was discovered in opj_j2k_write_sot in lib/openjp2/j2k.c in OpenJPEG 2.2.0. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service (heap-based buffer overflow affecting opj_write_bytes_LE in lib/openjp2/cio.c) or possibly remote code execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-14152.Show less

An exploitable code execution vulnerability exists in the image rendering functionality of Lexmark Perceptive Document Filters 11.3.0.2400. A specifically crafted PDF can cause a function call on a corrupted DCTStream to occur, resulting in user controlled data being written to the stack. A maliciously crafted PDF file can be used to trigger this vulnerability.Show less

An exploitable buffer overflow vulnerability exists in the tag parsing functionality of Ledger-CLI 3.1.1. A specially crafted journal file can cause an integer underflow resulting in code execution. An attacker can construct a malicious journal file to trigger this vulnerability.Show less

An off-by-one error was discovered in opj_tcd_code_block_enc_allocate_data in lib/openjp2/tcd.c in OpenJPEG 2.2.0. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service (heap-based buffer overflow affecting opj_mqc_flush in lib/openjp2/mqc.c and opj_t1_encode_cblk in lib/openjp2/t1.c) or possibly remote code execution.Show less

Ruby through 2.2.7, 2.3.x through 2.3.4, and 2.4.x through 2.4.1 can expose arbitrary memory during a JSON.generate call. The issues lies in using strdup in ext/json/ext/generator/generator.c, which will stop after encountering a '\0' byte, returning a pointer to a string of length zero, which is not the length stored in space_len.Show less

A memory allocation failure was discovered in the ReadPNMImage function in coders/pnm.c in GraphicsMagick 1.3.26. The vulnerability causes a big memory allocation, which may lead to remote denial of service in the MagickRealloc function in magick/memory.c.Show less

An Improper Restriction Of Operations Within The Bounds Of A Memory Buffer issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Researchers have identified multiple vulnerabilities that allow invalid locations to be referenced for the memory buffer, which may allow an attacker to execute arbitrary code or cause the system to crash.Show less

A stack-based buffer overflow issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Researchers have identified multiple vulnerabilities where there is a lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer, which could allow an attacker to execute arbitrary code under the context of the process.Show less

A heap-based buffer overflow issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Researchers have identified multiple vulnerabilities where there is a lack of proper validation of the length of user-supplied data prior to copying it to the heap-based buffer, which could allow an attacker to execute arbitrary code under the context of the process.Show less

Stack-based buffer overflow in "dnsproxy.c" in connman 1.34 and earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted response query string passed to the "name" variable.Show less
