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

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject variable offset alu on PTRTOFLOWKEYS For PTRTOFLOWKEYS, the checkflowkeysaccess function only uses a fixed offset for validation. However, the variable offset ptr isn’t prohibited for this type of pointer. Therefore,...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: A NULL pointer dereference issue was fixed in hnsrocemapmrsg. The function ibmapmrsg allows ULPs to specify NULL as the sgoffset argument. The driver needs to check whether the argument is a NULL pointer before...

Astra Linux – Vulnerability in Wireshark

In Wireshark versions 3.2.0 to 3.2.4, the GVCP dissector could enter an infinite loop. This issue was addressed in the epan/dissectors/packet-gvcp.c file by ensuring that the offset increased in all situations...

Astra Linux – Vulnerability in imagemagick

In the functions CatromWeights, MeshInterpolate, InterpolatePixelChannel, InterpolatePixelChannels, and InterpolatePixelInfo, which are all part of /MagickCore/pixel.c, there were multiple unconstrained pixel offset calculations that were used with the floor function. These calculations resulted ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: binder: A check for offset alignment was added in bindergetobject. Commit 6d98eb95b450 “binder: avoid potential data leakage when copying txn” introduced changes to the way binder objects are copied. As a result, the offset...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: block: Fixed an incorrect offset in biotruncate The biotruncate function clears the buffer outside of the last block of bdev. However, the current implementation of biotruncate uses the wrong offset for the page. As a result, it...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net/smc: Check smcdv2extoffset when receiving a proposal message. When receiving a proposal message from the server, the smcdv2extoffset field in the proposal message comes from the remote client, and cannot be fully trusted. Onc...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: vfio/platform: checking the bounds of read/write syscalls. The count and offset parameters are passed from user space without being checked. Only the offset parameter is capped at 40 bits, which can be used to read/write data...

Astra Linux – Vulnerability found in Python 3.11, Python 3.7, and Python 2.7

The ‘zipfile’ module does not check the validity of the offset value specified in the ZIP64 End of Central Directory EOCD Locator record. Instead, the ZIP64 EOCD record is assumed to be the previous record in the ZIP archive. This behavior could be exploited to create ZIP archives that are...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: erofs/zmap.c: Corrected incorrect offset calculation The effective offset to be added to the length was incorrectly calculated, resulting in iomap-length being set to 0, which triggered a WARNON in iomapiterdone. This issue was...

Astra Linux – Vulnerability in Wireshark

In Wireshark versions 3.2.0 to 3.2.7, the GQUIC dissector could crash. This issue was addressed in the epan/dissectors/packet-gquic.c file by correcting the implementation of offset advancement...

Astra Linux – Vulnerability in imagemagick

Due to a missing check for the 0 value of replaceextent, it is possible for the offset p to overflow in SubstituteString, potentially affecting application availability. This issue can be triggered by an input file crafted with ImageMagick. The flaw affects ImageMagick versions prior to 7.0.8-68...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Validate data run offset This adds sanity checks for the data run offset. We should ensure that the data run offset is valid before attempting to unpack the data; otherwise, we may encounter use-after-free errors or...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: be2net: Buffer overflow has been fixed in begetmoduleeeprom. becmdreadporttransceiverdata assumes that it is given a buffer that is at least PAGEDATALEN long, or twice that if the module supports SFF 8472. However, this is not...

Astra Linux – Vulnerability in xorg-server

A out-of-bounds write flaw was discovered in the xorg-x11-server. This issue arises due to an incorrect calculation of a buffer offset when copying data stored in the heap in the XIChangeDeviceProperty function in Xi/xiproperty.c, and in the RRChangeOutputProperty function in randr/rrproperty.c...

Astra Linux – Vulnerability in pillow

A issue was discovered in Pillow before 8.1.1. In TiffDecode.c, there is a negative-offset memcpy with an invalid size...

Astra Linux – Vulnerability in bluez

The clifeatreadcb function in src/gatt-database.c does not perform bounds checks on the 'offset' variable before using it as an index into an array for reading...

Astra Linux – Vulnerability in Vim

Use of out-of-range pointer offset in the GitHub repository vim/vim before version 8.2.4418...

Astra Linux – Vulnerability in Vim

Use of out-of-range pointer offset in the GitHub repository vim/vim before version 8.2.4440...

Astra Linux – Vulnerability in Qemu

A bug in QEMU could cause a guest I/O operation that is normally directed to an arbitrary disk offset to be directed instead to offset 0. This could potentially overwrite the VM’s boot code. For example, this could be exploited by L2 guests who have a virtual disk vdiskL2 stored on the virtual di...
