Package : qemu
Version : 1:3.1+dfsg-8+deb10u11
CVE ID : CVE-2020-24165 CVE-2023-0330 CVE-2023-3180
Debian Bug : 1029155
Multiple issues were discovered in qemu, a fast processor emulator.
CVE-2020-24165
A use-after-free race in the code generator could lead to the
execution of arbitrary code.
CVE-2023-0330
A DMA-MMIO reentrancy problem in the lsi53c895a device may lead to
memory corruption bugs, such as stack overflow or use-after-free.
CVE-2023-3180
The function virtio_crypto_sym_op_helper, part of the implementation
of qemu's virtual crypto device, did not check that the values of
'src_len' and 'dst_len' are the same. This could lead to a heap
buffer overflow.
For Debian 10 buster, these problems have been fixed in version
1:3.1+dfsg-8+deb10u11.
We recommend that you upgrade your qemu packages.
