Qemu: bt: Integer overflow in Bluetooth routines allows memory corruption

The Bluetooth subsystem in QEMU mishandles negative values for length variables, leading to memory corruption.

Code execution if run with command line switch -v

If the attacker manages to create files in the directory used to collect log files in supportutils before version 3.1-5.7.1 (e.g. with CVE-2018-19638) he can kill arbitrary processes on the local machine.

Code execution if run with command line switch -v

If supportutils before version 3.1-5.7.1 is run with -v to perform rpm verification and the attacker manages to manipulate the rpm listing (e.g. with CVE-2018-19638) he can execute arbitrary commands as root.

User can overwrite arbitrary log files in support tar

In supportutils, before version 3.1-5.7.1 and if pacemaker is installed on the system, an unprivileged user could have overwritten arbitrary files in the directory that is used by supportutils to collect the log files.

Static temporary filename allows overwriting of files

Supportutils, before version 3.1-5.7.1, wrote data to static file /tmp/supp_log, allowing local attackers to overwrite files on systems without symlink protection

Local root exploit via inclusion of attacker controlled shell script

Supportutils, before version 3.1-5.7.1, when run with command line argument -A searched the file system for a ndspath binary. If an attacker provides one at an arbitrary location it is executed with root privileges

gnuplot: buffer overflow in cairotrm_options function

An issue was discovered in cairo.trm in Gnuplot 5.2.5. This issue allows an attacker to conduct a buffer overflow with an arbitrary amount of data in the cairotrm_options function. This flaw is caused by a missing size check of an argument passed to the "set font" function. This issue occurs when the Gnuplot pngcairo terminal is used as a backend.

gnuplot: buffer overflow with an arbitrary amount of data in the PS_options

An issue was discovered in post.trm in Gnuplot 5.2.5. This issue allows an attacker to conduct a buffer overflow with an arbitrary amount of data in the PS_options function. This flaw is caused by a missing size check of an argument passed to the "set font" function. This issue occurs when the Gnuplot postscript terminal is used as a backend.

gnuplot: heap-based buffer overflow in df_generate_ascii_array_entry

An issue was discovered in datafile.c in Gnuplot 5.2.5. This issue allows an attacker to conduct a heap-based buffer overflow with an arbitrary amount of data in df_generate_ascii_array_entry. To exploit this vulnerability, an attacker must pass an overlong string as the right bound of the range argument that is passed to the plot function.

QEMU: 9pfs: crash due to race condition in renaming files

v9fs_wstat in hw/9pfs/9p.c in QEMU allows guest OS users to cause a denial of service (crash) because of a race condition during file renaming.

The WP Backup+ (aka WPbackupplus) plugin through 2018-11-22 for WordPress allows remote attackers to obtain sensitive information from server folders and files, as demonstrated by download.sql.

Qemu: 9pfs: Use-after-free due to race condition while updating fid path

hw/9pfs/cofile.c and hw/9pfs/9p.c in QEMU can modify an fid path while it is being accessed by a second thread, leading to (for example) a use-after-free outcome.

An issue was discovered in mod_alias_physical_handler in mod_alias.c in lighttpd before 1.4.50. There is potential ../ path traversal of a single directory above an alias target, with a specific mod_alias configuration where the matched alias lacks a trailing '/' character, but the alias target filesystem path does have a trailing '/' character.

QEMU: ppc64: Out-of-bounds r/w stack access in pnv_lpc_do_eccb

The pnv_lpc_do_eccb function in hw/ppc/pnv_lpc.c in Qemu before 3.1 allows out-of-bounds write or read access to PowerNV memory.

QEMU: lsi53c895a: OOB msg buffer access leads to DoS

In Qemu 3.0.0, lsi_do_msgin in hw/scsi/lsi53c895a.c allows out-of-bounds access by triggering an invalid msg_len value.

ImageMagick: memory leak in WriteMSLImage of coders/msl.c

There is a memory leak in the function WriteMSLImage of coders/msl.c in ImageMagick 7.0.8-13 Q16, and the function ProcessMSLScript of coders/msl.c in GraphicsMagick before 1.3.31.

elfutils: Divide-by-zero in arlib_add_symbols function in arlib.c

Divide-by-zero vulnerabilities in the function arlib_add_symbols() in arlib.c in elfutils 0.174 allow remote attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by eu-ranlib, because a zero sh_entsize is mishandled.

elfutils: eu-size cannot handle recursive ar files

An Invalid Memory Address Dereference exists in the function elf_end in libelf in elfutils through v0.174. Although eu-size is intended to support ar files inside ar files, handle_ar in size.c closes the outer ar file before handling all inner entries. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file.

Mozilla: Proxy Auto-Configuration file can define localhost access to be proxied

When proxy auto-detection is enabled, if a web server serves a Proxy Auto-Configuration (PAC) file or if a PAC file is loaded locally, this PAC file can specify that requests to the localhost are to be sent through the proxy to another server. This behavior is disallowed by default when a proxy is manually configured, but when enabled could allow for attacks on services and tools that bind to the localhost for networked behavior if they are accessed through browsing. This vulnerability affects Firefox < 65.

mozilla: Use after free in Skia

An integer overflow in path handling lead to a use after free in Skia in Google Chrome prior to 71.0.3578.80 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
