LibVNCClient is a library for easy implementation of a VNC client. In 0.9.15 and earlier, LibVNCClient's Tight encoding decoder uses fixed-size 2048-pixel scratch buffers for the Gradient filter, but it does not reject Tight rectangles whose width is larger than 2048 pixels. A malicious VNC serve...

Astra Linux – Vulnerability in Netty
In Netty 4.1.x before 4.1.46, the ZlibDecoders allowed unbounded memory allocation when decoding Zlib-encoded byte streams. An attacker could send a large Zlib-encoded byte stream to the Netty server, forcing the server to allocate all of its available memory to a single decoder...
Astra Linux – Vulnerability in zlib, libz-mingw-w64
Zlib versions up to 1.2.12 have a heap-based buffer over-read or buffer overflow issue in the inflate function within inflate.c, due to a large gzip header extra field. NOTE: Only applications that call inflateGetHeader are affected. Some common applications bundle the affected Zlib source code,...
Astra Linux – Vulnerability in gst-plugins-good1.0
DOS: Potential heap overwrite during MKV demuxing using Zlib decompression. Integer overflow occurs in the matroskademux element within the gstmatroskadecompressdata function, which can cause a segfault—or potentially a heap overwrite, depending on the libc and operating system. Depending on the...
