IBM Connections 5.0, 5.5, and 6.0 could allow a remote attacker to conduct phishing attacks, using an open redirect attack. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to spoof the URL displayed to redirect a user to a malicious Web site that would appear to be trusted. This could allow the attacker to obtain highly sensitive information or conduct further attacks against the victim. IBM X-Force ID: 135521.

IBM Integration Bus 9.0 and 10.0 could allow an attacker that has captured a valid session id to hijack another users session during a small timeframe before the session times out. IBM X-Force ID: 134164.

IBM Tivoli Key Lifecycle Manager 2.5, 2.6, and 2.7 could allow a remote attacker to conduct phishing attacks, using an open redirect attack. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to spoof the URL displayed to redirect a user to a malicious Web site that would appear to be trusted. This could allow the attacker to obtain highly sensitive information or conduct further attacks against the victim. IBM X-Force ID: 133562.

IBM Tivoli Key Lifecycle Manager 2.5, 2.6, and 2.7 is vulnerable to a XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources. IBM X-Force ID: 133540.

IBM Security Access Manager Appliance 8.0.0 and 9.0.0 could allow a remote attacker to conduct phishing attacks, using an open redirect attack. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to spoof the URL displayed to redirect a user to a malicious Web site that would appear to be trusted. This could allow the attacker to obtain highly sensitive information or conduct further attacks against the victim. IBM X-Force ID: 130676.

An issue was discovered in Mattermost Server before 4.0.0, 3.10.2, and 3.9.2, when used as an OAuth 2.0 service provider, Session invalidation was mishandled.

An issue was discovered in Mattermost Server before 4.2.0, 4.1.1, and 4.0.5, when used as an OAuth 2.0 service provider. It mishandles a deny action for a redirection.

An issue was discovered in Mattermost Server before 4.2.0, 4.1.1, and 4.0.5. It allows Phishing because an error page can have a link.

cPanel before 64.0.21 allows demo accounts to redirect web traffic (SEC-245).

cPanel before 64.0.21 allows demo accounts to execute code via Encoding API calls (SEC-242).

cPanel before 67.9999.103 allows an open redirect in /unprotected/redirect.html (SEC-300).

Shopware before 5.3.4 has a PHP Object Instantiation issue via the sort parameter to the loadPreviewAction() method of the Shopware_Controllers_Backend_ProductStream controller, with resultant XXE via instantiation of a SimpleXMLElement object.

poppler: Infinite recursion in fofi/FoFiType1C.cc:FoFiType1C::cvtGlyph() function allows denial of service

The FoFiType1C::cvtGlyph function in fofi/FoFiType1C.cc in Poppler through 0.64.0 allows remote attackers to cause a denial of service (infinite recursion) via a crafted PDF file, as demonstrated by pdftops.

Blackboard Learn (Since at least 17th of October 2017) has allowed Unvalidated Redirects on any signed-in user through its endpoints for handling Shibboleth logins, as demonstrated by a webapps/bb-auth-provider-shibboleth-BBLEARN/execute/shibbolethLogin?returnUrl= URI.

kernel: Infinite recursion in arch/arm64/include/asm/arch_timer.h:arch_timer_reg_read_stable macro allows local users to cause denial of service

The arch_timer_reg_read_stable macro in arch/arm64/include/asm/arch_timer.h in the Linux kernel before 4.13 allows local users to cause a denial of service (infinite recursion) by writing to a file under /sys/kernel/debug in certain circumstances, as demonstrated by a scenario involving debugfs, ftrace, PREEMPT_TRACER, and FUNCTION_GRAPH_TRACER.

ImageMagick: assertion failure in MogrifyImageList function in MagickWand/mogrify.c

An issue was discovered in ImageMagick 7.0.7. The MogrifyImageList function in MagickWand/mogrify.c allows attackers to cause a denial of service (assertion failure and application exit in ReplaceImageInList) via a crafted file.

exempi: assertion failure in VPXChunk class in XMPFiles/source/FormatSupport/WEBP_Support.cpp

An issue was discovered in Exempi before 2.4.3. The VPXChunk class in XMPFiles/source/FormatSupport/WEBP_Support.cpp does not ensure nonzero widths and heights, which allows remote attackers to cause a denial of service (assertion failure and application exit) via a crafted .webp file.

zsh: NULL dereference in cd in sh compatibility mode under given circumstances

In builtin.c in zsh before 5.4, when sh compatibility mode is used, there is a NULL pointer dereference during processing of the cd command with no argument if HOME is not set.

kernel: Deadlock caused in fs/ocfs2/file.c:ocfs2_setattr() can allow local users to cause a denial of service

The ocfs2_setattr function in fs/ocfs2/file.c in the Linux kernel before 4.14.2 allows local users to cause a denial of service (deadlock) via DIO requests.

kernel: mishandling reference counts associated with f2fs_wait_discard_bios calls allowing local attacker to cause denial of service

The f2fs implementation in the Linux kernel before 4.14 mishandles reference counts associated with f2fs_wait_discard_bios calls, which allows local users to cause a denial of service (BUG), as demonstrated by fstrim.
