GitPython: GitPython: Denial of Service via crafted commit author field
A flaw was found in GitPython. A remote attacker could exploit a regular expression denial of service ReDoS vulnerability by crafting a malicious commit object. Specifically, a malformed author field containing an unterminated angle bracket can cause excessive processing, leading to the exhaustio...
org.bouncycastle/bc-java: org.bouncycastle/bctls-fips: Bouncy Castle for Java: Denial of Service via unchecked DTLS handshake reassembler buffer allocation
A flaw was found in Bouncy Castle for Java. The DTLS Datagram Transport Layer Security handshake reassembler allocates buffers based on an unchecked 24-bit length value. A remote attacker could exploit this vulnerability by sending a specially crafted DTLS handshake message, leading to excessive...
google.golang.org/grpc: gRPC-Go: Denial of Service via malformed RPC requests
A flaw was found in gRPC-Go. Servers created with xds.NewGRPCServer can be exploited by a remote client sending a malformed RPC request that lacks the required :authority or Host headers. This can trigger an index-out-of-bounds panic, leading to the termination of the entire server process and a...
pillow: pillow: Denial of Service via out-of-bounds memory access on zero-width images
A flaw was found in Pillow. A remote attacker can cause a Denial of Service DoS by supplying a specially crafted image with a width of zero to an application performing morphology operations. Because Pillow fails to validate zero-width image geometry during these operations, it attempts an...
pillow: pillow: Denial of Service via crafted multi-frame image conversion
A flaw was found in Pillow. When converting multi-frame images into a multi-page PDF document, the library repeatedly scans previously assigned object identifiers, resulting in quadratic processing time. A remote attacker could exploit this vulnerability by supplying a crafted image with a large...
net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service
A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This...
pillow: pillow: Arbitrary code execution via JPEG encoder buffer overflow
A flaw was found in Pillow. A remote attacker could exploit a heap buffer overflow vulnerability to achieve arbitrary code execution or cause a Denial of Service DoS. This issue occurs when an application re-encodes an untrusted image into JPEG format while preserving specially crafted color...
net/textproto: mime/multipart: golang: golang: Denial of Service via memory limit bypass in multipart form parsing
A flaw was found in the mime/multipart and net/textproto packages in Go. A remote attacker could exploit this vulnerability by submitting a crafted multipart form request that bypasses configured memory limits when the remaining boundary limit is small. This issue allows the application to read a...
pillow: pillow: Denial of Service via repeated EXIF headers
A flaw was found in Pillow. When processing a specially crafted image with repeated Exchangeable Image File Format EXIF metadata headers, the library repeatedly copies and parses the data. A remote attacker could exploit this vulnerability by providing a malicious image file to an application tha...
pillow: Pillow: Denial of Service via out-of-bounds read in TIFF decoding
A flaw was found in Pillow. When processing Tagged Image File Format TIFF images, the library fails to properly validate buffer boundaries during tile and color decoding routines. A remote attacker could exploit this vulnerability by supplying a specially crafted TIFF file with conflicting metada...
pillow: pillow: Denial of Service via infinite loop during PDF page rewriting
A flaw was found in Pillow. This vulnerability allows a remote attacker to cause a Denial of Service DoS through an infinite loop during PDF page processing. When rewriting pages, the parser fails to detect circular references in the page tree hierarchy. By submitting a specially crafted PDF...
urllib3: urllib3: Denial of Service via unbounded memory allocation in chunk parser
A flaw was found in urllib3. This flaw allows a Denial of Service DoS through unbounded memory allocation when parsing chunk-encoded responses. A malicious server can send an excessively long chunk-size line without a newline, exhausting client memory and terminating the application...
pillow: pillow: Denial of Service via memory exhaustion from crafted GIF image
A flaw was found in Pillow. When parsing a crafted GIF image, the library fails to discard rejected frame dimensions after encountering an excessively large image exception. If an application catches this exception and continues processing the image, subsequent operations attempt to allocate memo...
com.fasterxml.jackson.core/jackson-databind: tools.jackson.core/jackson-databind: jackson-databind: CPU Denial of Service via unbounded numeric parsing
A flaw was found in jackson-databind. An unauthenticated attacker can trigger a denial of service DoS by exploiting an unbounded numeric parse vulnerability. This occurs during the deserialization of javax.xml.datatype.Duration or javax.xml.datatype.XMLGregorianCalendar fields from JSON strings,...
Critical: Red Hat Security Advisory: Satellite 6.19 security update
A security update for Red Hat Satellite is now available. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from the CVE links ...
com.fasterxml.jackson.core/jackson-core: Jackson-core: Denial of Service via unbounded StringBuilder growth during malformed token processing
A flaw was found in FasterXML jackson-core. This vulnerability allows a remote attacker to cause a Denial of Service DoS by providing a specially crafted, malformed token to the JsonFactory.createParserDataInput method. The UTF8DataInputJsonParser component, responsible for handling DataInput...
org.bouncycastle/bc-java: org.bouncycastle/bctls-fips: Bouncy Castle for Java: Denial of Service via unchecked DTLS handshake reassembler buffer allocation
A flaw was found in Bouncy Castle for Java. The DTLS Datagram Transport Layer Security handshake reassembler allocates buffers based on an unchecked 24-bit length value. A remote attacker could exploit this vulnerability by sending a specially crafted DTLS handshake message, leading to excessive...
openssl: heap buffer overflow in CMS key unwrapping
A flaw was found in OpenSSL. A crafted CMS Cryptographic Message Syntax message can cause an 8-byte out-of-bounds heap write when it is decrypted with CMSdecrypt. This issue occurs because the CMS decryption process incorrectly sizes the key-unwrap output buffer when using the AES-WRAP-PAD unwrap...
com.fasterxml.jackson.core/jackson-core: tools.jackson.core/jackson-core: jackson-core: Denial of Service via incomplete fix in async JSON parser
A flaw was found in jackson-core. A remote attacker can exploit an incomplete fix in the non-blocking JSON parser by streaming specially crafted JSON data in small chunks. This bypasses the intended number length constraint, causing the parser to accumulate excessive memory per connection. This...
net/http: golang: golang: Denial of Service via crafted HTTP Range headers
A flaw was found in the Go net/http package. A remote attacker can cause a Denial of Service DoS by sending an HTTP request containing a Range header with a large number of small byte ranges. When the server processes these ranges while serving content, it consumes an excessive amount of CPU...
