Practical Countermeasure against Attacks Exploiting Detection Efficiency Mismatch in Quantum Key Distribution

We demonstrate a practical countermeasure against a well-known class of attacks on quantum key distribution QKD systems that exploit detection efficiency mismatch, where the receiver's detectors do not exhibit identical responses to incoming photons across all degrees of freedom. This class of...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fixed UBSAN shift-out-of-bounds warnings If getnumsdmaqueues or getnumxgmisdmaqueues is 0, we perform a shift operation where the number of bits shifted equals the number of bits in the operand. This behavior is...

Astra Linux – Vulnerability in HAPProxy

A vulnerability related to uncontrolled resource consumption was discovered in HAProxy, which could cause the service to crash. This issue could allow an authenticated remote attacker to run a specially crafted malicious server within an OpenShift cluster. The most significant impact is related t...

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

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx4: This issue prevents shift wrapping in the setusersqsize function. The ucmd-logsqbbcount variable is controlled by the user, which means that the shift operation can cause wrapping. This issue can be fixed by using...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: lib/fonts: Fixed undefined behavior in bit shifting for getdefaultfont. Shifting a signed 32-bit value by 31 bits is undefined; therefore, the significant bit was changed to unsigned. The UBSAN warning “calltrace” is as follow...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: nilfs2: Fixed a shift-out-of-bounds/overflow issue in nilfssb2badoffset. The patch series “nilfs2: Fix UBSAN shift-out-of-bounds warnings during mount time” addresses this issue. The first patch fixes a bug reported by syzbot,...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd: fixed the potential integer overflow that could occur when shifting an int. The left shift of the 32-bit integer constant 1 is evaluated using 32-bit arithmetic, and then passed as a 64-bit function argument. In cas...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: gfs2: Check sbbsizeshift after reading the superblock. Fuzzers often modify sbbsizeshift, but in reality it’s very unlikely that this field would be corrupted on its own. Nevertheless, it should still be checked to avoid potentia...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: validate BOOT sectorsperclusters When the NTFS BOOT sectorsperclusters field is greater than 0x80, it represents a shift value. Ensure that the shift value is not too large before using it the maximum cluster size for...

Astra Linux – Vulnerability in openexr
