CWE-834

An issue was discovered in Xpdf 4.00. catalog->getNumPages() in AcroForm.cc allows attackers to launch a denial of service (hang caused by large loop) via a specific pdf file, as demonstrated by pdftohtml. This is mainly caused by a large number after the /Count field in the file.

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the BGP protocol dissector could go into a large loop. This was addressed in epan/dissectors/packet-bgp.c by validating Path Attribute lengths.

libjpeg 9c has a large loop because read_pixel in rdtarga.c mishandles EOF.

An issue was discovered in Free Lossless Image Format (FLIF) 0.3. An attacker can trigger a long loop in image_load_pnm in image/image-pnm.cpp.

ext4_protect_reserved_inode in fs/ext4/block_validity.c in the Linux kernel through 5.5.3 allows attackers to cause a denial of service (soft lockup) via a crafted journal size.

srs2.c in PostSRSd before 1.10 allows remote attackers to cause a denial of service (CPU consumption) via a long timestamp tag in an SRS address.
