Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick, specifically in the file MagickCore/quantum-export.c. An attacker who submits a crafted file processed by ImageMagick could trigger undefined behavior, resulting in values that are outside the range of the unsigned long long type, as well as a shift exponent...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU implementation of VMWare’s paravirtual RDMA device in versions prior to 6.1.0. The issue occurs when handling a “PVRDMAREGDSRHIGH” write from the guest, and it may result in a crash of QEMU or cause undefined behavior due to the access of an uninitialized pointer...

Astra Linux – Vulnerability in imagemagick

The function WritePALMImage in /coders/palm.c uses sizet type conversions in several parts of the calculation. This could lead to values that are outside the range of the representable type unsigned long, resulting in undefined behavior when a malicious input file is processed by ImageMagick...
