Vulnerabilidades

An issue was discovered in pixHtmlViewer in prog/htmlviewer.c in Leptonica before 1.75.3. Unsanitized input (rootname) can overflow a buffer, leading potentially to arbitrary code execution or possibly unspecified other impact.

Leptonica before 1.75.3 does not limit the number of characters in a %s format argument to fscanf or sscanf, which allows remote attackers to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a long string, as demonstrated by the gplotRead and ptaReadStream functions.

Dropbox Lepton 1.2.1 allows DoS (SEGV and application crash) via a malformed lepton file because the code does not ensure setup of a correct number of threads.

The allocate_channel_framebuffer function in uncompressed_components.hh in Dropbox Lepton 1.2.1 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a malformed JPEG image.

The write_ujpg function in lepton/jpgcoder.cc in Dropbox lepton 1.0 allows remote attackers to cause denial of service (out-of-bounds read) via a crafted jpeg file.

The build_huffcodes function in lepton/jpgcoder.cc in Dropbox lepton 1.0 allows remote attackers to cause denial of service (out-of-bounds write) via a crafted jpeg file.

The setup_imginfo_jpg function in lepton/jpgcoder.cc in Dropbox lepton 1.0 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted jpeg file.

The setup_imginfo_jpg function in lepton/jpgcoder.cc in Dropbox lepton 1.0 allows remote attackers to cause a denial of service (segmentation fault) via a crafted jpeg file.

The process_file function in lepton/jpgcoder.cc in Dropbox lepton 1.0 allows remote attackers to cause a denial of service (crash) via a crafted jpeg file.

Multiple cross-site scripting (XSS) vulnerabilities in LEPTON 1.1.3 and other versions before 1.1.4 allow remote attackers to inject arbitrary web script or HTML via the (1) message parameter to admins/login/forgot/index.php, or the (2) display_name or (3) email parameter to account/preferences.php.

SQL injection vulnerability in modules/news/rss.php in LEPTON before 1.1.4 allows remote attackers to execute arbitrary SQL commands via the group_id parameter.

Directory traversal vulnerability in account/preferences.php in LEPTON before 1.1.4 allows remote attackers to include and execute arbitrary files via a .. (dot dot) in the language parameter.

Cross-site scripting (XSS) vulnerability in WebsiteBaker before 2.8, as used in LEPTON and possibly other products, allows remote attackers to inject arbitrary web script or HTML via unknown vectors, a different vulnerability than CVE-2006-2307.
