A reachable Object::getString assertion in Poppler 0.72.0 allows attackers to cause a denial of service due to construction of invalid rich media annotation assets in the AnnotRichMedia class in Annot.c.

There is an illegal WRITE memory access at caca/file.c (function caca_file_read) in libcaca 0.99.beta19.

There is an illegal WRITE memory access at common-image.c (function load_image) in libcaca 0.99.beta19 for 1bpp data.

There is an illegal READ memory access at caca/dither.c (function get_rgba_default) in libcaca 0.99.beta19 for 24bpp data.

There is an illegal READ memory access at caca/dither.c (function get_rgba_default) in libcaca 0.99.beta19 for the default bpp case.

There is an illegal WRITE memory access at common-image.c (function load_image) in libcaca 0.99.beta19 for 4bpp data.

There is floating point exception at caca/dither.c (function caca_dither_bitmap) in libcaca 0.99.beta19.

XRef::getEntry in XRef.cc in Poppler 0.72.0 mishandles unallocated XRef entries, which allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted PDF document, when XRefEntry::setFlag in XRef.h is called from Parser::makeStream in Parser.cc.

hw/rdma/vmw/pvrdma_main.c in QEMU does not implement a read operation (such as uar_read by analogy to uar_write), which allows attackers to cause a denial of service (NULL pointer dereference).

hw/rdma/rdma_backend.c in QEMU allows guest OS users to trigger out-of-bounds access via a PvrdmaSqWqe ring element with a large num_sge value.

QEMU can have an infinite loop in hw/rdma/vmw/pvrdma_dev_ring.c because return values are not checked (and -1 is mishandled).

hw/rdma/vmw/pvrdma_cmd.c in QEMU allows create_cq and create_qp memory leaks because errors are mishandled.

hw/rdma/vmw/pvrdma_cmd.c in QEMU allows attackers to cause a denial of service (NULL pointer dereference or excessive memory allocation) in create_cq_ring or create_qp_rings.

libarchive version commit 9693801580c0cf7c70e862d305270a16b52826a7 onwards (release v3.2.0 onwards) contains a CWE-20: Improper Input Validation vulnerability in WARC parser - libarchive/archive_read_support_format_warc.c, _warc_read() that can result in DoS - quasi-infinite run time and disk usage from tiny file. This attack appear to be exploitable via the victim must open a specially crafted WARC file.

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 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.

LibVNC before commit 4a21bbd097ef7c44bb000c3bd0907f96a10e4ce7 contains null pointer dereference in VNC client code that can result DoS.

LibVNC before 8b06f835e259652b0ff026898014fc7297ade858 contains CWE-665: Improper Initialization vulnerability in VNC Repeater client code that allows attacker to read stack memory and can be abuse for information disclosure. Combined with another vulnerability, it can be used to leak stack memory layout and in bypassing ASLR
