📄 Description (English)

A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted `.solv` file containing negative size values in the `repo_add_solv` function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS).

🤖 AI Executive Summary

A heap buffer overflow vulnerability in libsolv allows attackers to cause denial of service by processing specially crafted .solv files with negative size values. The flaw occurs in the repo_add_solv function due to improper memory allocation validation.

📄 Description (Arabic)

تم اكتشاف ثغرة تجاوز المخزن المؤقت في مكتبة libsolv عند معالجة ملفات .solv المصممة بشكل خاص تحتوي على قيم حجم سالبة. يؤدي هذا إلى تخصيص ذاكرة أقل من المطلوب وكتابة خارج الحدود المسموحة. يمكن للمهاجمين استغلال هذه الثغرة لإحداث هجمات حرمان الخدمة.

🤖 ملخص تنفيذي (AI)

A heap buffer overflow in libsolv enables attackers to trigger denial of service attacks using malicious .solv files containing negative size values. The vulnerability stems from inadequate validation in the repo_add_solv function leading to undersized memory allocation.

🔧 Remediation Steps (English)
Update libsolv to the latest patched version immediately. Implement input validation to reject .solv files with negative size values. Restrict processing of .solv files from untrusted sources and monitor system logs for exploitation attempts.
🔧 خطوات المعالجة (العربية)
قم بتحديث libsolv إلى أحدث إصدار معدل فوراً. طبق التحقق من صحة المدخلات لرفض ملفات .solv التي تحتوي على قيم حجم سالبة. قيد معالجة ملفات .solv من مصادر غير موثوقة وراقب سجلات النظام لمحاولات الاستغلال.
