Astra Linux – Vulnerability in Capstone

Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and earlier, the length of Skipdata was not checked for bounds. As a result, a user-provided Skipdata callback could cause the csdisasm/csdisasmiter memcpy function to write more than 24 bytes into csinsn.bytes, leading to a heap buffe...

Astra Linux – Vulnerability in rsync

In rsync versions 3.0.1 through 3.4.1, the receivexattr function relies on an untrusted length value during a qsort call, resulting in a use-after-free vulnerability. The vulnerability is exploitable when rsync is executed with the -X option also known as --xattrs. On Linux, many but not all comm...

Astra Linux – Vulnerability in Waitress

Waitress version 1.3.1 allows for the smuggling of requests by sending the Content-Length header twice. Waitress would fold the two Content-Length headers together, and since it cannot convert the now comma-separated values into integers, it internally sets the Content-Length to 0. If two...

Astra Linux – Vulnerability in HAPProxy

HAProxy versions 2.0.32, 2.1.x, and 2.2.x through 2.2.30, 2.3.x and 2.4.x through 2.4.23, 2.5.x and 2.6.x before 2.6.15, 2.7.x before 2.7.10, and 2.8.x before 2.8.2 send empty Content-Length headers, violating section 8.6 of RFC 9110. In rare cases, an HTTP/1 server behind HAPProxy may interpret...

In the Linux kernel, the following vulnerability has been resolved: libceph: Use u32 for non-negative values in cephmonmapDecode This patch fixes unnecessary implicit conversions that change the signedness of bloblen and nummon in cephmonmapDecode. Currently, bloblen and nummon are signed int...

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

In the Linux kernel, the following vulnerability has been resolved: usb: aqc111: Check the packet for fixup for true limits. If a device sends a packet that lies between 0 and sizeofu64, the value passed to skbtrim as the packet length will wrap around, resulting in a very large value. The driver...
