CVE-2009-4895

A race condition was found in the abrt-dbus D-Bus service's ChownProblemDir method. ChownProblemDir opens the dump directory with DD_OPEN_READONLY and calls dd_chown to change ownership of all files to the caller's uid, succeeding even while post-create event handlers hold a write lock. This allows an attacker to gain filesystem-level control of the dump directory while privileged event scripts are still running.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-50 and 7.1.2-25, when passing incorrect arguments in the distort operation a null pointer deference will occur. This issue has been patched in versions 6.9.13-50 and 7.1.2-25.

InDesign Desktop versions 21.3, 20.5.3 and earlier are affected by a NULL Pointer Dereference vulnerability that could result in an application denial-of-service. An attacker could exploit this vulnerability to crash the application, leading to a denial-of-service condition. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

A flaw was found in Samba’s WINS server component when running as an Active Directory Domain Controller. The WINS protocol handlers for certain request types did not properly validate incoming packets, allowing an unauthenticated remote attacker to trigger a NULL pointer dereference and crash the WINS service using specially crafted UDP packets.

In the Linux kernel, the following vulnerability has been resolved: coresight: tmc-etr: Fix race condition between sysfs and perf mode When trying to run perf and sysfs mode simultaneously, the WARN_ON() in tmc_etr_enable_hw() is triggered sometimes: WARNING: CPU: 42 PID: 3911571 at drivers/hwtracing/coresight/coresight-tmc-etr.c:1060 tmc_etr_enable_hw+0xc0/0xd8 [coresight_tmc] [..snip..] Call trace: tmc_etr_enable_hw+0xc0/0xd8 [coresight_tmc] (P) tmc_enable_etr_sink+0x11c/0x250 [coresight_tmc] (L) tmc_enable_etr_sink+0x11c/0x250 [coresight_tmc] coresight_enable_path+0x1c8/0x218 [coresight] coresight_enable_sysfs+0xa4/0x228 [coresight] enable_source_store+0x58/0xa8 [coresight] dev_attr_store+0x20/0x40 sysfs_kf_write+0x4c/0x68 kernfs_fop_write_iter+0x120/0x1b8 vfs_write+0x2c8/0x388 ksys_write+0x74/0x108 __arm64_sys_write+0x24/0x38 el0_svc_common.constprop.0+0x64/0x148 do_el0_svc+0x24/0x38 el0_svc+0x3c/0x130 el0t_64_sync_handler+0xc8/0xd0 el0t_64_sync+0x1ac/0x1b0 ---[ end trace 0000000000000000 ]--- Since the enablement of sysfs mode is separeted into two critical regions, one for sysfs buffer allocation and another for hardware enablement, it's possible to race with the perf mode. Fix this by double check whether the perf mode's been used before enabling the hardware in sysfs mode. mode: [sysfs mode] [perf mode] tmc_etr_get_sysfs_buffer() spin_lock(&drvdata->spinlock) [sysfs buffer allocation] spin_unlock(&drvdata->spinlock) spin_lock(&drvdata->spinlock) tmc_etr_enable_hw() drvdata->etr_buf = etr_perf->etr_buf spin_unlock(&drvdata->spinlock) spin_lock(&drvdata->spinlock) tmc_etr_enable_hw() WARN_ON(drvdata->etr_buf) // WARN sicne etr_buf initialized at the perf side spin_unlock(&drvdata->spinlock) With this fix, we retain the check for CS_MODE_PERF in get_etr_sysfs_buf. This ensures we verify whether the perf mode's already running before we actually allocate the buffer. Then we can save the time of allocating/freeing the sysfs buffer if race with the perf mode.

In OpenStack Nova before 33.0.2, the server create API does not strip certain hint data. The resulting instance has no Placement allocation.

Improper access control in the social login connection endpoint in Devolutions Server 2026.2.5 allows an authenticated vault member to enumerate social login entry metadata to which they are not authorized via a crafted API request.

Improper access control in Devolutions Server 2026.2.5, 2026.1.21 allows an authenticated user to access attachments via folder duplication with inherited permissions.

A flaw was found in GnuTLS. The `gnutls_pkcs11_token_set_pin` function, used for changing the Security Officer PIN, can lead to a use-after-free vulnerability. This occurs when an attacker attempts to change the PIN with a NULL old PIN for a token that lacks a protected authentication path.

A flaw was found in the GNOME localsearch (previously known as tracker-miners) MP3 Extractor `tracker-extract-mp3` component. A remote attacker could exploit this heap buffer overflow vulnerability by providing a specially crafted MP3 file containing malformed ID3 tags. This incorrect length calculation during the parsing of performer tags can lead to a read beyond the allocated buffer, potentially causing a Denial of Service (DoS) due to a crash or enabling information disclosure.
