A vulnerability was detected in OGRECave Ogre up to 14.4.1. The impacted element is the function Ogre::LogManager::stream of the file /ogre/OgreMain/src/OgreLogManager.cpp. Performing manipulation of the argument mDefaultLog results in null pointer dereference. The attack must be initiated from a local position. The exploit is now public and may be used.

Conventional Changelog generates changelogs and release notes from a project's commit messages and metadata. Prior to version 2.0.0, @conventional-changelog/git-client has an argument injection vulnerability. This vulnerability manifests with the library's getTags() API, which allows extra parameters to be passed to the git log command. In another API by this library, getRawCommits(), there are secure practices taken to ensure that the extra parameter path is unable to inject an argument by ending the git log command with the special shell syntax --. However, the library does not follow the same practice for getTags() as it does not attempt to sanitize for user input, validate the given params, or restrict them to an allow list. Nor does it properly pass command-line flags to the git binary using the double-dash POSIX characters (--) to communicate the end of options. Thus, allowing users to exploit an argument injection vulnerability in Git due to the --output= command-line option that results with overwriting arbitrary files. This issue has been patched in version 2.0.0.
In the Linux kernel, the following vulnerability has been resolved: scsi: ses: Handle enclosure with just a primary component gracefully This reverts commit 3fe97ff3d949 ("scsi: ses: Don't attach if enclosure has no components") and introduces proper handling of case where there are no detected secondary components, but primary component (enumerated in num_enclosures) does exist. That fix was originally proposed by Ding Hui <dinghui@sangfor.com.cn>. Completely ignoring devices that have one primary enclosure and no secondary one results in ses_intf_add() bailing completely scsi 2:0:0:254: enclosure has no enumerated components scsi 2:0:0:254: Failed to bind enclosure -12ven in valid configurations such even on valid configurations with 1 primary and 0 secondary enclosures as below: # sg_ses /dev/sg0 3PARdata SES 3321 Supported diagnostic pages: Supported Diagnostic Pages [sdp] [0x0] Configuration (SES) [cf] [0x1] Short Enclosure Status (SES) [ses] [0x8] # sg_ses -p cf /dev/sg0 3PARdata SES 3321 Configuration diagnostic page: number of secondary subenclosures: 0 generation code: 0x0 enclosure descriptor list Subenclosure identifier: 0 [primary] relative ES process id: 0, number of ES processes: 1 number of type descriptor headers: 1 enclosure logical identifier (hex): 20000002ac02068d enclosure vendor: 3PARdata product: VV rev: 3321 type descriptor header and text list Element type: Unspecified, subenclosure id: 0 number of possible elements: 1 The changelog for the original fix follows ===== We can get a crash when disconnecting the iSCSI session, the call trace like this: [ffff00002a00fb70] kfree at ffff00000830e224 [ffff00002a00fba0] ses_intf_remove at ffff000001f200e4 [ffff00002a00fbd0] device_del at ffff0000086b6a98 [ffff00002a00fc50] device_unregister at ffff0000086b6d58 [ffff00002a00fc70] __scsi_remove_device at ffff00000870608c [ffff00002a00fca0] scsi_remove_device at ffff000008706134 [ffff00002a00fcc0] __scsi_remove_target at ffff0000087062e4 [ffff00002a00fd10] scsi_remove_target at ffff0000087064c0 [ffff00002a00fd70] __iscsi_unbind_session at ffff000001c872c4 [ffff00002a00fdb0] process_one_work at ffff00000810f35c [ffff00002a00fe00] worker_thread at ffff00000810f648 [ffff00002a00fe70] kthread at ffff000008116e98 In ses_intf_add, components count could be 0, and kcalloc 0 size scomp, but not saved in edev->component[i].scratch In this situation, edev->component[0].scratch is an invalid pointer, when kfree it in ses_intf_remove_enclosure, a crash like above would happen The call trace also could be other random cases when kfree cannot catch the invalid pointer We should not use edev->component[] array when the components count is 0 We also need check index when use edev->component[] array in ses_enclosure_data_process =====
