lrzsz: Integer overflow in src/zm.c:zsdata() causes crash in sz and can leak information to receiver

lrzsz before version 0.12.21~rc can leak information to the receiving side due to an incorrect length check in the function zsdata that causes a size_t to wrap around.

ghostscript: Stack-based out-of-bounds write in pdf_set_text_matrix function in gdevpdts.c

The set_text_distance function in devices/vector/gdevpdts.c in the pdfwrite component in Artifex Ghostscript through 9.22 does not prevent overflows in text-positioning calculation, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document.

In versions of mruby up to and including 1.4.0, an integer overflow exists in src/vm.c::mrb_vm_exec() when handling OP_GETUPVAR in the presence of deep scope nesting, resulting in a use-after-free. An attacker that can cause Ruby code to be run can use this to possibly execute arbitrary code.

kernel: Undefined behaviour with INT_MIN argument in kernel/signal.c:kill_something_info() allows for denial of service

The kill_something_info function in kernel/signal.c in the Linux kernel before 4.13, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service via an INT_MIN argument.

libreoffice: Out of bounds write in filter/ww8/ww8toolbar.cxx:SwCTBWrapper class allows for denial of service with crafted document

The SwCTBWrapper::Read function in sw/source/filter/ww8/ww8toolbar.cxx in LibreOffice before 5.4.6.1 and 6.x before 6.0.2.1 does not validate a customizations index, which allows remote attackers to cause a denial of service (heap-based buffer overflow with write access) or possibly have unspecified other impact via a crafted document that contains a certain Microsoft Word record.

libreoffice: Use-after-free in sdstor/stgstrms.cxx:StgSmallStrm class allows for denial of service with crafted document

sot/source/sdstor/stgstrms.cxx in LibreOffice before 5.4.5.1 and 6.x before 6.0.1.1 uses an incorrect integer data type in the StgSmallStrm class, which allows remote attackers to cause a denial of service (use-after-free with write access) or possibly have unspecified other impact via a crafted document that uses the structured storage ole2 wrapper file format.

Before WordPress 4.9.5, the version string was not escaped in the get_the_generator function, and could lead to XSS in a generator tag.

Before WordPress 4.9.5, the URL validator assumed URLs with the hostname localhost were on the same host as the WordPress server.

Before WordPress 4.9.5, the redirection URL for the login page was not validated or sanitized if forced to use HTTPS.

kernel: Undefined behavior in kernel/exit.c:kernel_wait4() function allows local denial of service

The kernel_wait4 function in kernel/exit.c in the Linux kernel before 4.13, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service by triggering an attempted use of the -INT_MIN value.

Cacti before 1.1.37 has XSS because it makes certain htmlspecialchars calls without the ENT_QUOTES flag (these calls occur when the html_escape function in lib/html.php is not used).

Cacti before 1.1.37 has XSS because it does not properly reject unintended characters, related to use of the sanitize_uri function in lib/functions.php.

The decode_init function in libavcodec/utvideodec.c in FFmpeg through 3.4.2 allows remote attackers to cause a denial of service (out of array read) via an AVI file.

plexus-archiver: arbitrary file write vulnerability / arbitrary code execution using a specially crafted zip file

plexus-archiver before 3.6.0 is vulnerable to directory traversal, allowing attackers to write to arbitrary files via a ../ (dot dot slash) in an archive entry that is mishandled during extraction. This vulnerability is also known as 'Zip-Slip'.

php-pear: Unsafe deserialization of data in Archive_Tar class

PEAR Archive_Tar version 1.4.3 and earlier contains a CWE-502, CWE-915 vulnerability in the Archive_Tar class. There are several file operations with `$v_header['filename']` as parameter (such as file_exists, is_file, is_dir, etc). When extract is called without a specific prefix path, we can trigger unserialization by crafting a tar file with `phar://[path_to_malicious_phar_file]` as path. Object injection can be used to trigger destruct in the loaded PHP classes, e.g. the Archive_Tar class itself. With Archive_Tar object injection, arbitrary file deletion can occur because `@unlink($this->_temp_tarname)` is called. If another class with useful gadget is loaded, it may possible to cause remote code execution that can result in files being deleted or possibly modified. This vulnerability appears to have been fixed in 1.4.4.

libarchive: Use after free in RAR decoder resulting in a denial of service

libarchive version commit 416694915449219d505531b1096384f3237dd6cc onwards (release v3.1.0 onwards) contains a CWE-416: Use After Free vulnerability in RAR decoder - libarchive/archive_read_support_format_rar.c that can result in Crash/DoS - it is unknown if RCE is possible. This attack appear to be exploitable via the victim must open a specially crafted RAR archive.

libarchive: Double free in RAR decoder resulting in a denial of service

libarchive version commit 416694915449219d505531b1096384f3237dd6cc onwards (release v3.1.0 onwards) contains a CWE-415: Double Free vulnerability in RAR decoder - libarchive/archive_read_support_format_rar.c, parse_codes(), realloc(rar->lzss.window, new_size) with new_size = 0 that can result in Crash/DoS. This attack appear to be exploitable via the victim must open a specially crafted RAR archive.

python-paramiko: Authentication bypass in auth_handler.py

Paramiko version 2.4.1, 2.3.2, 2.2.3, 2.1.5, 2.0.8, 1.18.5, 1.17.6 contains a Incorrect Access Control vulnerability in SSH server that can result in RCE. This attack appear to be exploitable via network connectivity.

okular: Directory traversal in function unpackDocumentArchive() in core/document.cpp

okular version 18.08 and earlier contains a Directory Traversal vulnerability in function "unpackDocumentArchive(...)" in "core/document.cpp" that can result in Arbitrary file creation on the user workstation. This attack appear to be exploitable via he victim must open a specially crafted Okular archive. This issue appears to have been corrected in version 18.08.1

sympa version 6.2.16 and later contains a CWE-601: URL Redirection to Untrusted Site ('Open Redirect') vulnerability in The "referer" parameter of the wwsympa.fcgi login action. that can result in Open redirection and reflected XSS via data URIs. This attack appear to be exploitable via Victim's browser must follow a URL supplied by the attacker. This vulnerability appears to have been fixed in none available.
