When libcurl is asked to perform automatic gzip decompression of content-encoded HTTP responses with the CURLOPTACCEPTENCODING option, using zlib 1.2.0.3 or older, an attacker-controlled integer overflow would make libcurl perform a buffer overflow...

Security Bulletin: Denial of Service in urllib3 via Unbounded Decompression of Redirect Responses

Summary urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on t...

Security Bulletin:urllib3 Unbounded Decompression Chain Enables Denial of Service

Summary urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.24 and prior to 2.6.0, the number of links in the decompression chain was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps leading to high CPU usage and massiv...

CVE-2026-6535

A flaw was found in Wireshark's dissection engine. A remote attacker could exploit this vulnerability by sending a specially crafted packet. This could trigger a zlib decompression crash, leading to a denial of service and making the application unresponsive or causing it to terminate unexpectedl...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: erofs: Fix for lz4 inplace decompression Currently, EROFS can map another compressed buffer for inplace decompression, which was used to handle cases where some pages of compressed data are not actually in-place I/O. However, lik...

Astra Linux – Vulnerability in openexr

A flaw was discovered in OpenEXR in versions prior to 3.0.0-beta. A specially crafted input file provided by an attacker, when processed by the Dwa decompression functionality of OpenEXR’s IlmImf library, could lead to a NULL pointer dereferencing error. The most severe consequence of this...

Astra Linux – Vulnerability in curl

curl 7.84.0 supports “chained” HTTP compression algorithms, which means that a server response can be compressed multiple times, possibly using different algorithms. The number of allowable “links” in this “decompression chain” is unlimited, allowing a malicious server to insert virtually an...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: LZ4: fixed the issue of partial reading beyond the bounds of the buffer during decoding. During partialDecoding, an EOF occurs if either the output buffer is full or if reading further beyond the offset is not possible. In some...

Astra Linux – Vulnerability in curl

There is a vulnerability in curl v7.88.0 where resource allocation without limits or throttling exists. This vulnerability stems from the “chained” HTTP compression algorithms. This means that a server’s response can be compressed multiple times, possibly using different algorithms. The number of...
