CVE-2026-88051 Tesseract: Heap out-of-bounds write in GenericVector<T>::read due to independent reserved/size_used_ fields

Tesseract is an open source OCR engine. In version 5.5.3 and earlier, the callback form of GenericVector::read in src/ccutil/genericvector.h reads the independent int32 fields reserved and sizeused from a .traineddata model without a cap or an invariant check. reservereserved allocates the backin...

commons-configuration: Apache Commons Configuration: Denial of Service via uncontrolled recursion with crafted YAML input

A flaw was found in Apache Commons Configuration. When processing an untrusted configuration file, a remote attacker could provide specially crafted YAML input with cycles. This could lead to an uncontrolled recursion, causing a StackOverflowError and resulting in a Denial of Service DoS for the...

netty: io.netty/netty-codec-http: Netty: Incorrect HTTP response parsing leads to data confusion

A flaw was found in Netty, an asynchronous, event-driven network application framework. A remote attacker could exploit this vulnerability by sending a specific sequence of HTTP responses 103, followed by a 200 with a GET body, then another 200 for a HEAD request when the client pipelines GET the...

CVE-2026-88047 Tesseract: ReadNormProtos stack buffer overflow

Tesseract is an open source OCR engine. In version 5.5.3 and earlier, Classify::ReadNormProtos in src/classify/normmatch.cpp parses the NORMPROTO component of a .traineddata file and uses std::istream::operatorchar to extract a whitespace-delimited token into a fixed 61-byte stack buffer without...

CVE-2019–11043: PHP-FPM Nginx Remote Code Execution Vulnerability Vulnerability Description and Impact CVE-2019–11043 is a remote code execution RCE vulnerability. It affects PHP-FPM, which is a FastCGI Process Manager that is commonly used with Nginx web servers. The flaw arises from inadequate...

Excelize: Negative shared-string index causes panic in GetCellValue and GetRows

Negative shared-string index causes panic in GetCellValue and GetRows Summary Excelize parses shared-string cell values with strconv.Atoi and checks only the upper bound before indexing the shared string slice. If an XLSX file contains a shared-string cell with -1, the parsed index is negative. T...

CVE-2026-15461

Zephyr RTOS HL78xx modem GNSS driver contains a type confusion caused by a struct member offset mismatch: struct gnss_nmea0183_match_data was placed as the second member instead of the first, so NMEA parse callbacks read and write state at a shifted offset. The GSV callback reads a bogus pointer ...

apr-util: Apache Portable Runtime Utility: Denial of Service via XML stack recursion attack

A flaw was found in Apache Portable Runtime Utility apr-util. A remote attacker could exploit a stack recursion vulnerability by providing specially crafted XML input to a library consumer that uses the aprxmlquoteelem function. This could lead to a denial of service DoS due to an application cra...

net/url: Incorrect parsing of IPv6 host literals in net/url

The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...

CVE-2026-87961 ESP32-audioI2S 3.4.4 through 4.0.0 Heap-based Out-of-Bounds Read via Shadowed Length Parameter in read_ID3_Header

ESP32-audioI2S versions 3.4.4 through 4.0.0 contain a heap-based out-of-bounds read vulnerability in the readID3Header function due to a shadowed length parameter in ID3 synchronized-lyrics processing. Attackers can craft malicious MP3 files or HTTP audio streams with oversized frame size...

OSEC-2026-20 Cstruct indexing bugs can corrupt filtered output and reverse parsing results

Several functions in cstruct may use wrong data, leading to unexpected exceptions and return corrupted data. Impact - Cstruct.filtermap writes retained bytes at their original input positions, producing corrupted output when earlier bytes are dropped. - Cstruct.tail rev:true removes two bytes...

CVE-2026-42806

An out-of-bounds read vulnerability exists in the Bosch BME690 SensorAPI C-driver (v1.0.3 and prior) within the read_all_field_data function (bme69x.c). The driver prefetches heater configuration registers into a 30-byte stack buffer, but the gas_index field is extracted with a 4-bit mask (0–15) ...
