kernel: powerpc: local user can read vector registers of other users' processes via an interrupt

In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via an interrupt. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE is misused in arch/powerpc/kernel/process.c.

In JetBrains Hub versions earlier than 2018.4.11436, there was no option to force a user to change the password and no password expiration policy was implemented.

The Recruitment module in Humanica Humatrix 7 1.0.0.681 and 1.0.0.203 allows remote attackers to access all candidates' information on the website via a modified selApp variable to personalData/resumeDetail.cfm. This includes personal information and other sensitive data.

An issue was discovered in PRiSE adAS 1.7.0. The OPENSSO module does not properly check the goto parameter, leading to an open redirect that leaks the session cookie.

Ansible: malicious code could craft filename in nxos_file_copy module

A vulnerability was found in Ansible Engine versions 2.9.x before 2.9.3, 2.8.x before 2.8.8, 2.7.x before 2.7.16 and earlier, where in Ansible's nxos_file_copy module can be used to copy files to a flash or bootflash on NXOS devices. Malicious code could craft the filename parameter to perform OS command injections. This could result in a loss of confidentiality of the system among other issues.

kernel: incomplete fix for race condition between mmget_not_zero()/get_task_mm() and core dumping in CVE-2019-11599

The fix for CVE-2019-11599, affecting the Linux kernel before 5.0.10 was not complete. A local user could use this flaw to obtain sensitive information, cause a denial of service, or possibly have other unspecified impacts by triggering a race condition with mmget_not_zero or get_task_mm calls.

A vulnerability was found in Moodle 3.7 to 3.7.3, 3.6 to 3.6.7, 3.5 to 3.5.9 and earlier where an open redirect existed in the Lesson edit page.

ghostscript: -dSAFER escape in .charkeys (701841)

A flaw was found in all versions of ghostscript 9.x before 9.50, where the `.charkeys` procedure, where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. An attacker could abuse this flaw by creating a specially crafted PostScript file that could escalate privileges within the Ghostscript and access files outside of restricted areas or execute commands.

mod_auth_openidc: Open redirect in logout url when using URLs with leading slashes

A flaw was found in mod_auth_openidc before version 2.4.0.1. An open redirect issue exists in URLs with trailing slashes similar to CVE-2019-3877 in mod_auth_mellon.

nbdkit: assertion failure by issuing commands in the wrong order

A denial of service vulnerability was discovered in nbdkit. A client issuing a certain sequence of commands could possibly trigger an assertion failure, causing nbdkit to exit. This issue only affected nbdkit versions 1.12.7, 1.14.1, and 1.15.1.

krb5: reversed strlcpy() allows client to crash the KDC

A flaw was found in, Fedora versions of krb5 from 1.16.1 to, including 1.17.x, in the way a Kerberos client could crash the KDC by sending one of the RFC 4556 "enctypes". A remote unauthenticated user could use this flaw to crash the KDC.

libnbd: remote code execution vulnerability

Structured reply is a feature of the newstyle NBD protocol allowing the server to send a reply in chunks. A bounds check which was supposed to test for chunk offsets smaller than the beginning of the request did not work because of signed/unsigned confusion. If one of these chunks contains a negative offset then data under control of the server is written to memory before the read buffer supplied by the client. If the read buffer is located on the stack then this allows the stack return address from nbd_pread() to be trivially modified, allowing arbitrary code execution under the control of the server. If the buffer is located on the heap then other memory objects before the buffer can be overwritten, which again would usually lead to arbitrary code execution.

A vulnerability was found in Moodle 3.7 to 3.7.1, 3.6 to 3.6.5, 3.5 to 3.5.7 and earlier unsupported versions, where forum subscribe link contained an open redirect if forced subscription mode was enabled. If a forum's subscription mode was set to "forced subscription", the forum's subscribe link contained an open redirect.

A vulnerability was found in Moodle 3.7 to 3.7.1, 3.6 to 3.6.5, 3.5 to 3.5.7 and earlier unsupported versions, where the mobile launch endpoint contained an open redirect in some circumstances, which could result in a user's mobile access token being exposed. (Note: This does not affect sites with a forced URL scheme configured, mobile service disabled, or where the mobile app login method is "via the app").

ipa: Session not terminated after logout

A flaw was found in FreeIPA versions 4.5.0 and later. Session cookies were retained in the cache after logout. An attacker could abuse this flaw if they obtain previously valid session cookies and can use this to gain access to the session.

ghostscript: Safer mode bypass by .forceput exposure in .pdfexectoken and other procedures (701450)

A flaw was found in, ghostscript versions prior to 9.50, in the .pdfexectoken and other procedures where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

ghostscript: Safer mode bypass by .forceput exposure in setsystemparams (701443)

A flaw was found in ghostscript, versions 9.x before 9.50, in the setsystemparams procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

ghostscript: Safer mode bypass by .forceput exposure in setuserparams (701444)

A flaw was found in all ghostscript versions 9.x before 9.50, in the .setuserparams2 procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

ghostscript: Safer mode bypass by .forceput exposure in .pdf_hook_DSC_Creator (701445)

A flaw was found in, ghostscript versions prior to 9.50, in the .pdf_hook_DSC_Creator procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.
