Исправить файловые конфликты между пакетами

In GNU Chess 6.2.5, there is a stack-based buffer overflow in the cmd_load function in frontend/cmd.cc via a crafted chess position in an EPD file.

GNU Chess 6.2.7 allows attackers to execute arbitrary code via crafted PGN (Portable Game Notation) data. This is related to a buffer overflow in the use of a .tmp.epd temporary file in the cmd_pgnload and cmd_pgnreplay functions in frontend/cmd.cc.

Уязвимость функции squashfs_opendir компонента unsquash-1.c набора инструментов для создания и извлечения файловых систем Squashfs Squashfs-Tools, связанная с недостатками ограничения имени пути к каталогу, позволяющая нарушителю нарушить целостность данных, а также вызвать отказ в обслуживании

Уязвимость функции squashfs_opendir компонента unsquash-2.c набора инструментов для создания и извлечения файловых систем Squashfs Squashfs-Tools, связанная с неверным определением символических ссылок перед доступом к файлу, позволяющая нарушителю нарушить целостность данных, а также вызвать отказ в обслуживании

squashfs_opendir in unsquash-1.c in Squashfs-Tools 4.5 stores the filename in the directory entry; this is then used by unsquashfs to create the new file during the unsquash. The filename is not validated for traversal outside of the destination directory, and thus allows writing to locations outside of the destination.

squashfs_opendir in unsquash-2.c in Squashfs-Tools 4.5 allows Directory Traversal, a different vulnerability than CVE-2021-40153. A squashfs filesystem that has been crafted to include a symbolic link and then contents under the same filename in a filesystem can cause unsquashfs to first create the symbolic link pointing outside the expected directory, and then the subsequent write operation will cause the unsquashfs process to write through the symbolic link elsewhere in the filesystem.

Уязвимость программного обеспечения, предоставляющая в сеть службу протокола динамической конфигурации хоста DHCP, связанная с выходом операции за границы буфера в памяти, позволяющая нарушителю вызвать отказ в обслуживании

In ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16, ISC DHCP 4.4.0 -> 4.4.2 (Other branches of ISC DHCP (i.e., releases in the 4.0.x series or lower and releases in the 4.3.x series) are beyond their End-of-Life (EOL) and no longer supported by ISC. From inspection it is clear that the defect is also present in releases from those series, but they have not been officially tested for the vulnerability), The outcome of encountering the defect while reading a lease that will trigger it varies, according to: the component being affected (i.e., dhclient or dhcpd) whether the package was built as a 32-bit or 64-bit binary whether the compiler flag -fstack-protection-strong was used when compiling In dhclient, ISC has not successfully reproduced the error on a 64-bit system. However, on a 32-bit system it is possible to cause dhclient to crash when reading an improper lease, which could cause network connectivity problems for an affected system due to the absence of a running DHCP client process. In dhcpd, when run in DHCPv4 or DHCPv6 mode: if the dhcpd server binary was built for a 32-bit architecture AND the -fstack-protection-strong flag was specified to the compiler, dhcpd may exit while parsing a lease file containing an objectionable lease, resulting in lack of service to clients. Additionally, the offending lease and the lease immediately following it in the lease database may be improperly deleted. if the dhcpd server binary was built for a 64-bit architecture OR if the -fstack-protection-strong compiler flag was NOT specified, the crash will not occur, but it is possible for the offending lease and the lease which immediately followed it to be improperly deleted.
